Koishi Petty 150mm

The Koishi line features a stainless steel kurouchi finish. The kurouchi finish at the top of the knife helps keep these knives relatively low maintenance when compared with other Japanese carbon knives. The edge of the blade, however, will form a patina as it is made from Aogami Super Steel. Hardened up to 63:65 Rockwell, edge retention of these blades is outstanding. 

This 150mm petty measures about 5.875 inches in blade length and is more of a standard size petty than the 75mm, with 120-150mm being typical. This knife is ideal for small prep work like mincing shallots or garlic, or even cleaning up a tenderloin.
