This 190mm ProCut San-Mai Gyuto represents a large step forward in my polishing abilities. In this blade the various hues of carbon diffusion are visible at the weld interface while the cladding itself carries a natural mural of alloy banding patterns that exist within the steel itself.

Blade Special Features

Fully convex ground blade, stainless clad with active banding.

ProCut is a brand new steel released by Pop’s Knife Supply and Larrin Thomas. You could think of ProCut as a steel with the toughness of 80CrV2, the nickel content of 15n20 and edge retention somewhere between 52100 and AEB-L. 

This 190mm ProCut San-Mai Gyuto features a stone tuned geometry and a very fine 2500 grit finish that was polished with my own special mixture that results in a kasumi-like finish without the use of uchigumori. This finish highlights the core steel while creating a smokey haze where some minor carbon migration has occurred and reveals the endogenous banding within the cladding steel.
