Blade length: 213mm Blade thickness: slightly less than 2mm Double-edged This is the work of a craftsman from Yamagata, known as a "field blacksmith," who makes traditional Japanese knives. The steel used is Aogami No. 2, providing exceptional sharpness and ease of use. I purchased this directly from the workshop several years ago, but the supply of tsuba (handguards) has been delayed, and they are not planning to make any more of this particular model with a tsuba, making it very rare. Furthermore, the hammered pattern is not only stylish but also improves food release from the blade, making it practical. Recently, I've found single-edged knives easier to use, so I'm selling this to declutter. I've priced it at the lowest possible price, so no price reductions are possible. I have sharpened it up to a #8000 grit stone from Kitayama, so you can use it immediately upon arrival.
