safe and durable certificate of authenticity included with every sword we stand behind our craftsmanship frequently asked questions what does “clay-tempered” mean? clay tempering is a traditional japanese technique. the smith coats the blade in clay before quenching — thin on the edge, thick on the spine. when quenched, the edge cools fast (gets hard) and the spine cools slow (stays flexible). this creates the hamon (temper line) and makes a blade that’s both hard and flexible. is the hamon real? yes. it’s formed naturally during the clay-tempering process. it’s not etched, not laser-engraved, not fake. each blade has a unique hamon pattern — like a fingerprint. what is t10 steel? t10 is a high carbon tool steel (about 1.0% carbon). it can reach 60+ hrc hardness and holds a good edge. it’s a common choice for modern katana that use traditional forging methods. is this sword full tang? yes. the tang (nakago) runs the full length of the handle. this is the traditional and safest construction for a functional katana. can i cut with this sword? this is a collector-grade sword. it can cut, but we recommend it for display, collection, and light practice (suburi, iaido kata). if you want to do tameshigiri (target cutting), contact us about swords made specifically for that. what’s special about the tsuba? it’s pure copper with a six-petal flower shape — that shape is rare for katana tsuba. the surface is hand-hammered (tsuchime), so it has tons of small dimples that catch the light. it’s exclusive to ab sword and not available from other makers. is the saya finish durable? yes. it’s multiple coats of lacquer over a solid wood core. the metallic speckle pattern is embedded in the lacquer — it won’t wear off under normal handling. the lacquer is smooth and glossy. is this legal in my country? sword laws vary. in many places, ornamental (blunt) swords are legal, but sharpened blades may be restricted. check your local laws before ordering. we ship as a collectible item. contact us if you need the blade blunted for legal reasons. how do i care for the blade? wipe it with a soft dry cloth after handling. oil it every few weeks with choji oil (or gun oil / mineral oil). don’t touch the blade with bare hands — finger oils cause rust. store it in a cool, dry place away from humidity. does it come with a certificate? yes. every sword comes with a certificate of authenticity from ab sword. it describes the materials and construction. as a handmade item, minor variations in hamon and hada are normal — that’s how you know it’s hand-forged. *,
