This is a wrought iron gyuto with 1.2519 core. This steel is similar to aogami #2. This knife has a Kasumi finish done by myself on Japanese natural stones. It also provides an easily thinned knife. The wrought iron polishes extremely well on japanese natural stones. The polish was finished on my ohira suita. The handle of this knife is composed of a single piece of curly yellow stringy bark from Australia. This knife would be a perfect candidate for kasumi polishing on Japanese natural stones due to the already stone worked bevels. The wrought iron on this knife was sourced from an antique wagon wheel. I would consider this a workhorse.
