TangGu Sword

A functional katana does not need to begin at the highest end of the market, but as buyers move from entry-level Maru blades to Sanmai, Kobuse, Oroshigane, and CPM 3V models, the differences in steel, blade construction, polishing, fittings, and overall koshirae quality generally become more noticeable. Based on TangGu Sword’s current catalog, entry-level Maru katana are priced at approximately AUD 500–700 (USD 350–490), mid-range Sanmai models at approximately AUD 1,300–2,600 (USD 910–1,820), and Kobuse and Oroshigane models at approximately AUD 1,500–3,000 (USD 1,050–2,100). First-time buyers usually focus on finding a sword that is structurally reliable, consistently made, and suitable for practical use, while more experienced collectors and practitioners are often willing to pay more for more complex blade construction, tougher steels, more refined fittings, and a higher overall level of finish. If you are unsure which steel, blade construction, or price range is best suited to your needs, please email us for more professional advice based on your budget, intended use, and personal preferences.

For most first-time buyers, a well-made Maru blade is usually the best starting point. Many buyers look for a first katana that is reasonably priced, dependable, and not overly specialized. TangGu Sword’s Maru range provides a straightforward entry-level choice, offering practical performance, reliable construction, and a variety of designs to suit different aesthetic preferences. It is an ideal option for buyers who want a functional and well-made first katana without needing to navigate more complex blade constructions or premium materials.

When choosing a katana, the first consideration should be its primary purpose. Buyers who mainly want a sword for collecting or display will usually place greater emphasis on the hamon, saya lacquer, fittings, polish, and overall traditional appearance. Those planning to use the sword for iaido training, kenjutsu practice, or tameshigiri should pay closer attention to blade construction, steel toughness, heat treatment, blade geometry, and the security of the tsuka and mountings. Choosing the steel and price range after defining the intended use will usually make it easier to find the right sword. Buyers who value traditional aesthetics and craftsmanship may prefer a Sanmai, Kobuse or Oroshigane Blade with a genuine hamon and traditional laminated construction, while frequent cutters may be better suited to a simpler, reliable modern monosteel blade, such as T10 high-carbon steel or 9260 spring steel, or a high-performance model made from a high-toughness steel such as CPM 3V.

The price differences between TangGu Sword katana mainly reflect blade construction, steel type, forging and heat-treatment requirements, polishing quality, and the overall standard of the koshirae, rather than decoration alone. Entry-level Maru katana use a relatively straightforward monosteel construction and can still provide dependable practical performance, while higher-priced models may feature more complex blade structures such as Sanmai, Kobuse, or Oroshigane, which generally require additional forging steps, more careful material combinations, and tighter process control. Some premium models also use higher-cost modern steels such as CPM 3V, which require more specialized heat treatment, together with more refined polishing, hand-fitted mountings, horn-reinforced components, hishigami-supported tsukamaki, upgraded fuchi-kashira, menuki, tsuba, and more elaborate saya lacquer work. The final price therefore reflects not only visual detail, but also the difficulty of blade production, material cost, skilled labour, fitting precision, and the overall level of finish.

If you would like to receive your katana sooner and prefer a complete, established configuration, an in-stock model from TangGu Sword is usually the more straightforward choice, especially for first-time buyers. Stocked models allow customers to clearly review the blade, fittings, and overall appearance before purchasing, while reducing uncertainty during the selection process. A custom katana is better suited to buyers who already have a clear understanding of their needs and want greater control over the steel, blade construction, hamon, saya lacquer, tsuba, fittings, and tsuka wrapping. TangGu Sword offers blade structures such as Maru-zukuri, Sanmai, Kobuse, and Gomai, together with a range of modern steels and Oroshigane options. Custom orders therefore allow for a more individual combination of performance and aesthetics, but they generally require a longer production period and more decisions regarding intended use, budget, and configuration.

Whether a folded-steel or laminated katana is worth choosing depends mainly on how much the buyer values traditional blade construction, visible hada, forging complexity, and overall collectability. A more complex construction should not automatically be understood as superior in every situation. Maru blades use a relatively straightforward monosteel construction and are generally known for consistent performance, simplicity, and ease of maintenance. Sanmai and Kobuse blades combine steels with different properties to create more traditional laminated structures, while Oroshigane blades place greater emphasis on hand-refined steel, repeated forging, and traditional craftsmanship. Paying more for a folded or laminated model makes sense for buyers who genuinely appreciate its forging method, surface character, and craftsmanship, rather than simply because the terminology sounds more prestigious. For customers who place greater priority on practical use, dependable performance, and value, a well-made and properly heat-treated Maru monosteel katana can also be an excellent choice.

T10, 9260, folded steel, and Oroshigane each suit different types of buyers, and no single material is universally the best for every purpose. T10 high-carbon steel is generally well suited to buyers who value a genuine hamon, relatively high hardness, and good edge retention. When properly clay tempered and heat-treated, it can offer a strong balance between traditional appearance and practical performance. 9260 spring steel is known for its toughness, impact resistance, and greater forgiveness in use, making it a suitable choice for those who prioritize durability and dependable performance. Folded steel is repeatedly forged and folded to create visible hada patterns, and its main appeal lies in its traditional appearance, craftsmanship, and visual depth; however, the number of folds alone does not mean it will outperform a well-made monosteel blade. Oroshigane blades place greater emphasis on hand-refined steel, repeated forging, traditional blade construction, and the expression of hada and craftsmanship, making them especially suitable for buyers who value traditional methods, artistic character, and collectability. The best choice should therefore be based on intended use, cutting frequency, maintenance habits, aesthetic preferences, and performance requirements, rather than on the steel name or the apparent complexity of the forging process alone.

Maru-zukuri, Sanmai, and Kobuse describe different blade constructions, while Oroshigane refers to steel that has been hand-refined and repeatedly forged. Maru-zukuri uses a single steel throughout the blade, resulting in a relatively straightforward construction with consistent performance and easier control over heat treatment and overall quality. Sanmai typically combines a harder core steel with relatively softer outer layers, aiming to balance edge hardness, blade toughness, and the craftsmanship of a traditional laminated structure. Kobuse generally uses a harder outer jacket around a more flexible core, allowing the blade to maintain a hard surface and cutting edge while benefiting from a tougher internal structure. Oroshigane is not a separate blade construction; it is TangGu Sword’s hand-refined steel, produced through material refinement, repeated folding and forging, and impurity control, and it can then be used in traditional constructions such as Kobuse. Put simply, Maru-zukuri, Sanmai, and Kobuse explain how the blade is assembled and structured, while Oroshigane explains how the steel itself is refined and produced.

Whether the hamon on a TangGu Sword katana is genuine depends on the specific blade and product description. Many Maru-zukuri, Sanmai, and Kobuse katana made from high-carbon steel are differentially heat-treated through clay tempering, producing a genuine hardening line and visible hamon. Blades made from certain modern high-performance steels that are not suited to traditional differential hardening may instead feature a decorative hamon created through hand polishing or finishing. TangGu Sword clearly states how the hamon is produced on each relevant product page, helping customers distinguish between a genuine clay-tempered hamon, a polished hamon effect, and other decorative treatments. A genuine hamon is not only a visual pattern; it also reflects structural changes between the hardened edge and the rest of the blade caused by differential heat treatment. A decorative hamon is primarily intended to recreate a traditional appearance and does not indicate that the blade has been clay tempered. Please review the individual product description carefully before purchasing, or email TangGu Sword for a more detailed and professional explanation.

A bo-hi removes a portion of material from the blade, reducing its overall weight and changing the katana’s balance, stiffness, and handling characteristics, but this does not mean that a blade with a bo-hi is automatically too weak. Its practical effect depends on the depth, width, and placement of the groove, as well as the blade thickness, geometry, steel, heat treatment, and overall workmanship. A blade with a bo-hi is usually lighter and easier to handle, and it may produce a clearer tachikaze during a properly executed swing, making it suitable for users who value agility, speed, and training feel. A blade without a bo-hi retains a fuller cross-section and generally provides a more substantial sense of weight and greater stiffness, which may appeal to buyers who prefer a more solid and stable blade. The choice between bo-hi and hi-nashi should therefore be based on intended use, personal handling preference, and the overall blade design, rather than judging the strength or quality of a katana solely by whether it has a groove.

Niku Convex Geometry refers to a blade geometry that retains additional material behind the cutting edge and gradually curves outward before narrowing toward the edge. Compared with a thinner or flatter edge profile, an appropriate amount of niku provides greater support behind the edge, improving resistance to impact and reducing the risk of rolling or chipping during harder cutting or slightly misaligned strikes. This makes it particularly suitable for users who prioritize durability, bamboo cutting, or more demanding practical use. However, greater niku can also increase resistance as the blade passes through a target, so it may not move through tatami, rolled mats, or other soft targets as easily as a thinner edge geometry. More niku is not automatically better; its performance also depends on the steel, heat treatment, blade thickness, polishing accuracy, and the user’s cutting technique. The best choice should balance edge durability with cutting efficiency according to the intended target and use.

On a katana, “full tang” generally means that the nakago extends securely into the tsuka and is held in place through the correct traditional mounting system. The tang is fitted into a wooden tsuka core shaped to match it and is secured with one or more mekugi. However, the safety and reliability of a katana depend on more than the length of the tang alone. Important factors also include the thickness and shape of the nakago, the fit between the tang and the tsuka core, the condition and security of the mekugi, and the overall assembly of components such as the habaki, seppa, tsuba, and fuchi. For this reason, a katana should be judged by how securely and accurately the tang, handle, and mounting system work together, rather than by the “full tang” label alone.

Steel type is important, but heat treatment, blade geometry, polishing quality, mounting security, and the accuracy of the product description often have a greater influence on a katana’s actual performance than the steel name alone. Even a blade made from a premium steel may have reduced durability, cutting performance, or safety if the heat treatment is poor, the edge geometry is unsuitable, the polishing is rough, or the tsuka and mounting system are not fitted securely. By contrast, a katana made from a more common steel can still provide dependable and excellent practical performance when it is properly heat-treated, well-shaped, and correctly assembled. Buyers should therefore look beyond labels such as T10 or 9260 and consider the heat-treatment method, blade construction, edge geometry, tsuka-core fit, mekugi security, overall mounting quality, and whether the product description is clear and transparent. TangGu Sword focuses on achieving the right balance between steel, craftsmanship, assembly quality, and intended use, rather than judging a sword’s quality by the steel name alone.

TangGu Sword katana primarily use two traditional styles of tsukamaki: Morohineri-maki（諸捻巻）and Morotsumami-maki（諸摘巻）. For TangGu Sword katana made from July 2026 onward, Japanese-made pure silk tsuka-ito（正絹柄糸）is used as standard unless otherwise stated on the product page or a different special material is selected by the customer. Every tsuka is wrapped by a professional tsukamaki craftsman using traditional Japanese methods, including proper tension control, alternating crossovers, hishigami placement, menuki positioning, and final-knot finishing. A properly completed tsukamaki should meet the standards of tightness, alignment, uniformity, stability, and comfort: the tsuka-ito should remain firmly in position, the diamond openings should be naturally and evenly aligned, the tension should be consistent throughout, and the final knots should remain secure while providing a comfortable and reliable grip.

TangGu Sword places folded paper supports, known as hishigami（菱紙）, beneath the crossover points of the tsuka-ito. Hishigami support the edges of the wrapping, help preserve the shape of the diamond openings, and distribute tension more evenly across the tsuka, reducing the likelihood of the wrapping collapsing, becoming distorted, or loosening over time. The menuki are securely positioned beneath the wrapping, and the final knots are threaded and tightened using traditional methods.

A katana should be cleaned and given a fresh, thin coat of protective oil after it has been touched, used for drawing practice, or used for cutting. Even when it is kept mainly for collection or display, the blade should still be inspected regularly, as the ideal maintenance frequency depends on humidity, climate, storage conditions, and how often the sword is handled. In a relatively dry environment, checking the blade every few weeks may be sufficient, while humid or coastal conditions usually require more frequent inspection. During maintenance, remove old oil, fingerprints, moisture, and residue with a clean, soft cloth, then apply a very light and even layer of neutral rust-preventive oil. Avoid applying too much oil, as excess oil may run into the saya and trap dust or moisture. In simple terms, whenever the blade has been touched, used, exposed to moisture, or left unchecked for an extended period, it should be cleaned and re-oiled to reduce the risk of rust and corrosion on the carbon-steel blade.

For katana maintenance, a very thin layer of neutral rust-preventive oil is usually sufficient, and a traditional choji oil maintenance kit is not always necessary. Light mineral oil or a dedicated sword-care oil is generally the safest choice. Some simple sewing-machine oils may also be suitable, but the product should not contain abrasive ingredients, aggressive solvents, or additives that may become sticky or dry into a residue. Traditional choji oil is usually mineral oil with a small amount of fragrance added, so its main purpose is still to create a moisture-resistant protective layer on high-carbon steel. Regardless of the oil used, the key is not to apply more, but to first remove old oil, fingerprints, and moisture, then use a clean, soft cloth to spread a very thin and even protective film over the blade. Excess oil may run into the saya, attract dust, or trap moisture, making future maintenance more difficult.

It is best to avoid touching a polished katana blade with bare hands, as sweat, salts, and natural skin oils can remain on the surface of the high-carbon steel, leaving fingerprints and increasing the risk of staining, oxidation, or rust. Even when no immediate change is visible, fingerprints may gradually develop into dark spots or corrosion marks. If the blade is accidentally touched, use a clean, soft, lint-free cloth to remove fingerprints and moisture as soon as possible, then apply a very thin and even layer of neutral rust-preventive oil. When inspecting, cleaning, or maintaining a katana, hold it by the tsuka or another safe area away from the cutting edge, and always handle the blade carefully to avoid injury.

To prevent a katana from rusting in humid conditions, keep the blade clean and dry, protect it with a very thin and even layer of rust-preventive oil, and store the sword in a well-ventilated environment with stable humidity and minimal temperature fluctuation. High-carbon steel is sensitive to sweat, moisture, and airborne humidity, so avoid touching the blade with bare hands and remove fingerprints, moisture, and old oil after handling, drawing practice, or cutting before applying a fresh protective layer. In humid, coastal, or rainy-season conditions, inspect the blade more frequently than you would in a dry climate. A dehumidifier or replaceable desiccant may be used near the storage area, but the desiccant should not touch the blade or be placed deep inside the saya. Applying excess oil does not provide better protection and may allow oil to run into the saya, where it can attract dust or trap moisture. Avoid long-term storage in basements, garages, near bathrooms or windows, or in other places with significant changes in temperature and humidity. Regular inspection, correct light oiling, and stable storage conditions can greatly reduce the risk of staining, discoloration, and corrosion.

For most katana collectors and practitioners, storing the blade inside the saya is normal and appropriate, but the most important point is to ensure that the blade is clean, dry, and protected with only a very thin layer of rust-preventive oil before it is sheathed. If fingerprints, moisture, cutting residue, or excess oil remain on the blade, they may increase the risk of staining or rust inside the enclosed saya. On the other hand, leaving the blade exposed for long periods can make it more vulnerable to airborne humidity, dust, and accidental contact, so open display is not necessarily safer than storing it in the saya. The correct approach is to remove old oil and residue, apply a light protective film, store the sword in an environment with stable humidity and minimal temperature fluctuation, and inspect both the blade and the inside of the saya regularly. Avoid using too much oil, as excess oil may run into the saya, attract dust, or accumulate over time. Whether the katana is stored in its saya or displayed temporarily, cleanliness, humidity control, and regular inspection are the key factors in preventing rust and protecting the blade.

Routine cleaning, wiping, and oiling generally do not require a katana to be disassembled. Disassembly should only be carried out carefully when there is a genuine need to inspect the nakago, address a loose tsuka, repair the mountings, or replace the mekugi. A traditional katana relies on a precise fit between the tang, wooden tsuka core, and mekugi to remain secure, and frequent or incorrect disassembly may wear the mekugi, damage the inside of the tsuka, alter the original fit, or cause looseness and rattling after reassembly. Owners who are unfamiliar with katana construction should not remove the tsuka simply for routine maintenance. If a newly received sword has a loose handle, damaged mekugi, moving fittings, or any other assembly issue, stop using it and email TangGu Sword for professional inspection and advice rather than repeatedly taking it apart or attempting repairs yourself.

TangGu Sword offers shipping to the United States, Europe, Canada, New Zealand, and Australia. Eligible sword orders qualify for free standard shipping; however, this offer does not apply to koshirae components purchased separately, such as saya, tsuba, fuchi-kashira, menuki, tsuka-ito, or other sword fittings. Shipping charges for these accessories are calculated at checkout based on the destination and parcel details. TangGu Sword maintains stock in Australia and can provide Express Shipping for eligible Australian orders; current availability and any express delivery charges should be confirmed on the product page or at the time of ordering. Katana orders shipped to the United States are generally arranged on a Delivered Duty Paid (DDP) basis, which means the applicable import charges are usually included in the shipping arrangement and reduces the likelihood of additional customs fees after delivery. Import regulations, VAT, customs duties, and sword restrictions vary between European countries, so European orders should not be assumed to be duty-paid in all cases, and customers may be responsible for charges collected by their local customs authority. Before ordering, please confirm the laws governing the import, purchase, and possession of swords in your country or region. If you are unsure whether TangGu Sword can ship to your destination, or would like more information about stock availability, Express Shipping, delivery times, duties, or customs clearance, please email us for more accurate shipping advice.

TangGu Sword accepts return requests within 30 days of the customer receiving the order, provided that the item remains unused, in its original condition and packaging, and is accompanied by valid proof of purchase. Before returning an item, customers must first email TangGu Sword to obtain return approval and shipping instructions; items sent back without prior authorization may not be accepted. Unless the item is defective or incorrect, return shipping is generally the customer’s responsibility, and a restocking fee, transaction fee, or other applicable charge may be deducted depending on the circumstances of the order.

Under TangGu Sword’s return policy, custom katana made to the customer’s specifications, as well as items featuring engraving, names, text, special dimensions, custom colour combinations, or other personalized details, are generally not eligible for return, exchange, or cancellation due to a change of mind. This is because custom products are individually made according to the customer’s confirmed requirements, including the steel, blade construction, dimensions, hamon, saya lacquer, tsuba, fittings, tsuka wrapping, and other selected details, and usually cannot be resold as standard inventory once completed. Customers should therefore review all specifications, designs, measurements, and engraved text carefully before confirming a custom order and should email TangGu Sword for professional advice if any detail is unclear. Exceptions may apply where there is a confirmed manufacturing error, quality issue, or a material difference from the final approved specifications. All cases are handled in accordance with TangGu Sword’s return policy.

Before shipment, TangGu Sword individually inspects every katana, including the blade, saya, tsuka, mekugi, and other mounting components, and provides the customer with photos or videos for review and confirmation. If your TangGu Sword katana arrives with shipping damage, a visible quality issue, missing components, or an item that does not match your order, please stop using it immediately and contact us by email as soon as possible.

As every katana is handcrafted, minor variations are natural and cannot be completely avoided. Small differences may appear in details such as the exact shape of the hamon, the size or alignment of the tsukamaki diamonds, the wood grain, the texture of the saya lacquer, and the appearance of hand-finished fittings. Provided that these variations do not affect the sword’s safety, structural integrity, or normal function, they are generally not considered quality defects. Rust, staining, or corrosion that develops after delivery due to fingerprints, moisture, insufficient cleaning, unsuitable storage conditions, or improper maintenance is also not considered a manufacturing defect. However, if rust or corrosion is already present when the katana is received, please contact us immediately for inspection and assessment.

If an eligible issue is discovered after delivery, please provide your order number, photographs of the outer packaging and shipping label, and clear photos or videos showing the damage, defect, missing component, or incorrect item. Please retain all original packaging, protective materials, accessories, and included components, and do not disassemble, repair, polish, sharpen, or modify the katana, as these actions may affect our assessment of the issue and the available resolution. TangGu Sword will review each case individually and, in accordance with our shipping and return policies, may provide technical support, repair, replacement, shipment of missing components, or a refund where appropriate. We recommend inspecting the blade, tsuka, saya, mekugi, and other mounting components as soon as the package is received and contacting us immediately if anything appears unusual.

In general, adults may legally purchase a katana in most parts of the United States and keep it in a private residence for collecting, display, training, or other lawful purposes. There is no single nationwide licence or permit required specifically for purchasing a katana. Katanas imported from overseas can also generally be declared and cleared as sword products. TangGu Sword and the shipping carrier handle the relevant export declarations, shipping documentation, and U.S. customs-clearance procedures, so American customers do not normally need to arrange or worry about these processes themselves.

However, legally purchasing and keeping a katana in a private residence does not necessarily mean that it may be freely carried in public. Rules concerning open carry, concealed carry, transportation in a vehicle, and bringing a katana into schools, government buildings, courthouses, airports, or other restricted locations may vary by state, county, and city. Customers should therefore check the current laws and regulations in their state and local area concerning the purchase, possession, transportation, and carrying of swords, and should use the katana only for lawful and safe purposes.

TangGu Sword cannot provide legal advice or replace guidance from local law-enforcement authorities or a qualified lawyer. Customers who are uncertain about local requirements should contact their local police department or an appropriately qualified legal professional for confirmation.

In general, whether it is legal to purchase and possess a katana in Australia depends on the customer’s state or territory, as the laws governing swords are not the same throughout the country. In some states and territories, adults may generally purchase and securely keep a katana in a private residence for collecting, display, martial arts training, or other lawful purposes. However, in more strictly regulated jurisdictions such as Victoria and South Australia, swords may be classified as prohibited or controlled weapons, and purchasers or owners may need to obtain the relevant permit or approval, or qualify for a legal exemption relating to collecting, martial arts, education, inheritance, or another recognised purpose.

TangGu Sword will check the basic delivery requirements based on the shipping address provided by the customer. However, customers remain responsible for confirming before placing an order that they are legally permitted to purchase and possess a katana in their state or territory, and for obtaining any required permit, approval, or exemption documentation in advance. If local laws do not allow the customer to legally receive or possess the relevant product, TangGu Sword may be unable to arrange shipment.

Even where private purchase and possession are legal, this does not mean that a katana may be freely carried in public. When transporting a katana to martial arts training, an exhibition, repair service, or another lawful activity, it should be secured in its saya and enclosed packaging and transported directly to the intended destination. It should not be displayed in public or carried without a lawful reason. Stricter rules generally apply in schools, courthouses, government buildings, airports, public transport facilities, and other restricted locations.

As laws may change across Australian states and territories, customers should check the latest requirements with the police authority in their state or territory before purchasing. TangGu Sword cannot provide legal advice or replace confirmation from local law-enforcement authorities regarding whether an individual qualifies for a permit or exemption.
