This blade is 1/16″ thick 440C. Designed for Walter V., this is the fourth knife I’ve made for him over the years as he is a serious kitchen enthusiast!! All different designs based on his design ideas. The handle is stained and finished with Polymerized Tung Oil. It looks like a varnish but it isn’t and it doesn’t chip. As the handle wears, it’s easy to reapply the oil as needed. A quick scuff with some steel wool will give you a satin look.
