At one time I worked on a friends ranch ( free housing and I took care of the horses) and was able to carry a fixed blade all day every day . It was a Camillus Navy Mark 1 with the fiberglass sheath, 51/2" of honest tool steel. It was more than enough knife for anything I ran into on a regular basis on the ranch. By the way, I paid 4 dollars and some change for it at a surplus store (well, it WAS 1969 after all) and I still have it. It's still a reliable sharp tool too.
