I am not using my Shigefusa Santoku because it doesn’t have a usable tip like Gyuto does & it’s too flat. My plan is in the picture below, shown between my 180 & 160mm Gyuto, to repofile it into a 170mm Carter style Funayuki instead. I do like the hefty weight, the taller height, the steel, thick spine start & strong distal taper. I like the convex grind bevel, I’ll maintain convex grind but thin it behind edge. has anyone done this? thoughts?
