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. Kasumi finishes are not very common among western makers. They are very time consuming, but the end result is absolutely worth it. It also provides an easily thinned and polished knife. The wrought iron polishes extremely well on japanese natural stones. The handle of this knife is composed of a figured piece of dyed Hawaiian Mango. The wood handle has some blue/grey streaking throughout the block. 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. The polish was finished on my ohira suita.
