Mora Original Classic #1. Before the introduction of modern plastics, many Mora knife sheaths were made of a fiber called "Unica". The belt tab has the traditional button hole attachment. The 3 3/4" blade is laminated carbon steel with a full length tang secured at the pommel with a collar. It's about .102" thick. The handle is unfinished birch, and a bit smaller then the regular Classic #1. The weight with the sheath is only about 2 3/4 ounces, I think it would make an excellent neck knife. There is only a few left.
