The Masakage Koishi is hand forged from Aogami super steel and cladded in stainless steel. Very consistent heat treatment with a rockwell of 63-64 hrc. The koishi holds a very high reputation in professional kitchens for its long lasting edge and smooth cutting feel.
These knives have been named Koishi (pebbles) as the tsuchime finish gives the impression of river pebbles. Finished with a cherry wood octagonal handle.
