This is a san mai gyuto with 1.2519 core. This steel is similar to aogami #2. The cladding is heavily banded A203E, this is a high nickel and low carbon alloy. I would consider this knife to fit into a ‘midweight’ category. This knife has a slightly convex wide bevel grind. This knife was etched in a weak acid which shows the banding quite clearly. The handle of this knife is a single piece of figured ironwood.
