The Companion is made using 8670 steel. It's a tough and easily sharpened low alloy, carbon, steel that takes and holds a very sharp edge. The white G 10 handle is handsome, strong, and provides a secure grip. Hollow carbon-fiber pins. Made to be a "daily companion," this knife is extremely versatile. Comes with hand-made, fitted leather sheath. Fully hand-made custom built by Michael Presnell.
