Tsuchime is basically the word used for "hammered" in Japanese. These knives are clad with this unique hammered Tsuchime pattern, and use VG-5 steel on the edge that's heat treated to 60 Rockwell. Light and easy to use, these knives will take a very nice edge and are easy to care for. The nice, western handle is made with black pakka wood with a nice stainless steel bolster attached. This is a very nice knife indeed for something in this price range.
