This Tetsuhiro nakiri measures 165mm on the edge and has a beautiful tsuchime (hammered) finish. The blade is san mai (clad) constructed with white #1 steel as the core steel. Beautiful looks and great performance. We had them upgrade the handle on these to magnolia wood in an octagonal shape with buffalo horn ferrule. They also have a really nice engraving on the blade. Edge on this knife is pretty much evenly ground as is the entire blade so it will be good for lefties and righties alike.
