This is a wrought iron with 26c3 core. 26c3 is a fine grained high carbon steel that is great for chef knives. The wrought iron on this knife is from an antique wagon wheel. The handle of this knife is composed of Australian Ringed Mulga and an African Blackwood ferrule. This knife definitely has a workhorse grind to it that is slightly higher than I would do for my low bevel kasumi. After working the bevel on stones I satin finished the blade and etched in a light acid, I then removed most of the oxides with a natural stone mud. This has left a nicely contrasting finish with a lot of wrought iron character exposed.
