O1 Tool Steel is a low alloy American carbon steel. It has a proven reputation for edge holding and ease of sharpening. Desert Ironwood (Olneya tesota) is a tree that grows in the Sonoran Desert of Northern Mexico and Southern Arizona. It is extremely dense and stable. Ivory Micarta is a paper-based phenolic composite that is incredibly durable and stable


The full tang construction means the blade extends throughout the handle. This is the strongest way to construct a knife. The handle is held together by two stainless steel corby bolts and top quality marine epoxy. The handle features a countersunk lanyard hole. A handmade 6oz vegetable tanned leather sheath is included.


Carbon steel oxidizes when exposed to moisture, acids or bases. This is easily removed with fine steel wool or a Scotch-Brite pad. Keeping a light layer of food-safe oil on the blade will protect it, although some oxidation will protect the blade in the form of a patina.
