Hand forged from W2 tool steel, with a four inch, flat ground blade and razor sharp convex edge. The cutting edge is RC 61.5, while the spine is unhardened and super tough, giving a combination factory knives can’t touch. Gimping on the thumb and spine add registration and security. The Arizona ironwood handle is secured with two copper corby bolts and a lanyard tube. Includes a tight fitting slip sheath crafted from 8 oz leather and oiled for protection from the elements.. A satisfyingly clean and simple design with great capability in the field. Easy to carry, use and admire.
