Frequently Asked Questions

What does the fold-forging process contribute to a folding katana's blade quality?
The fold-forging process in traditional Japanese katana construction serves several purposes that contribute to the final blade quality. In historical Japanese sword-making, the primary steel available - tamahagane smelted from iron sand - contained inconsistent carbon distribution and slag inclusions that needed to be refined through repeated folding and forge-welding. Each fold doubles the layer count and, through the hammering process, works out slag inclusions while redistributing carbon more evenly through the steel. A billet folded ten times produces over a thousand layers of steel with refined grain structure and more consistent carbon distribution than the starting material. In modern T10 carbon steel folding katana, the starting material is already refined steel rather than raw tamahagane, so the fold-forging process functions more as a traditional craft technique that refines grain structure and creates the fine, dense surface texture that allows the subsequent clay tempering and polishing to produce a clearly defined hamon. The fold-forging contributes to the overall blade quality and the surface characteristics that make the hamon visible.
What hamon patterns are found in folding katana from this collection?
Hamon patterns in folding katana from this collection vary from piece to piece because each hamon is individually created by the clay application technique used on that specific blade. The most common hamon patterns include suguha - a straight or nearly straight hamon running parallel to the blade edge - which is the simplest and most classical pattern, associated with restraint and traditional swordsmanship. Notare hamon feature gentle, flowing wave-like undulations that give the temper line an organic, fluid quality. Gunome hamon have a more regular, tooth-like or notched wave pattern that repeats along the blade length. Choji hamon feature clove-shaped or irregular projections from the main hamon line, considered among the most visually elaborate traditional patterns. Within each pattern type, the specific nie and nioi activity - the crystalline and misty zones visible at the hamon boundary under magnification or raking light - varies from blade to blade, making each folding katana individually unique in its hamon character.
How do I examine and appreciate the hamon on a folding katana?
Examining and appreciating the hamon on a folding katana requires specific lighting conditions that reveal the temper line's full character and detail. The most effective examination method is to hold the blade horizontally and tilt it slightly while directing a concentrated light source - a desk lamp or flashlight - along the blade flat from the spine side at a low angle. As the blade tilts, the hamon will appear as a white or misty zone along the lower blade section, with the nie activity - fine bright crystalline particles - and nioi activity - the misty or cloudy zone - becoming visible within and around the hamon boundary. Under this raking light examination, details that are invisible in overhead lighting become apparent: the specific wave pattern of the hamon, projections and inlets in the boundary line, and the activity within the hamon zone itself. A magnifying glass or loupe increases the visibility of nie and nioi activity significantly. The hamon examination technique is one of the most rewarding aspects of T10 clay-tempered katana collecting.
How do I clean and maintain a T10 folding katana to preserve the hamon?
Maintaining a T10 clay-tempered folding katana to preserve the hamon requires a careful cleaning routine that protects the polished blade surface without abrading the crystalline structure of the hamon zone. After every handling session, use a soft lint-free cloth to remove fingerprints and moisture from the full blade surface, working from the spine toward the edge rather than across the blade. Apply a thin coat of camellia oil or choji oil - the traditional Japanese blade oil - to the full blade surface, ensuring the oil reaches the hamon zone, then buff away excess with a soft cloth. Never use metal polishing compounds, abrasives, or any aggressive cleaning materials on a polished hamon blade: the nie and nioi activity in the hamon zone is created by the specific crystalline structure of the steel surface, and abrasion will permanently damage or obscure this structure. If the blade develops light surface oxidation on the body of the blade away from the hamon, gentle cleaning with uchiko polishing powder applied with a soft cotton ball can address minor oxidation without damaging the surface. Store in a low-humidity environment, away from temperature extremes.

Sword looks beautiful but did come with a couple rusty spots. They offered a little discount and that made me happier. The sword was sharp but not as sharp as I thought it would be from the reviews and description according to the page. Overall still a beautiful sword that looks well made!

TrueKatana has adequate blades, primarily T10... best bang for your buck; especially for tameshigiri.r
r
When you order your sword, pray that nothing ever goes wrong because the company has ZERO customer service.r
r
I've ordered 11 swords from this company. Despite that, they NEVER tried to make amends for selling me a shinobi sword once that was fucked up beyond repair. When I lodged my reasonable complaint, they acted like I was full of shit.r
r
Any decent company would spare NO expense in satisfiying a good customer. Not TrueKatana... they know their customer base needs what they have so they punish you for it.

I rarely leave reviews, but my experience with TrueKatana absolutely deserves one.r
r
I initially received an incorrect item with my order. Mistakes happen, that part didn’t concern me. What did matter was how the situation was handled, and TrueKatana exceeded every expectation I had.r
r
From the very first reply, their support team was polite, responsive, and genuinely focused on making things right. They clearly communicated my options, worked with my timeline (this was a birthday gift), and went out of their way to minimize inconvenience. Instead of rigid policies or delays, I was met with flexibility, transparency, and solutions.r
r
The highlight? They arranged shipment of the correct sword promptly and ultimately told me I could keep the incorrect item at no cost—no return required. That level of trust and goodwill is rare, especially in online retail.r
r
What impressed me most wasn’t just the resolution, but how easy they made the entire process feel. No friction. No defensiveness. No hoops to jump through. Just professional, thoughtful customer care from start to finish.r
r
TrueKatana has earned a customer for life. Their customer service genuinely rivals what I’ve experienced with top-tier Fortune 500 companies, and I wouldn’t hesitate to recommend them to anyone considering a purchase.r
r
If you’re on the fence, don’t be. You’ll be taken care of.
