This is a truly versatile blade. I got this from one of our Negrito instructors when I was going through jungle training in the Philippines over 40 years ago. It is made from a truck leaf spring, and can cut 4" bamboo, skin a monkey, or trim your finger nails. A heck of a lot better survival tool than our standard issue Ka-Bars.
Come to think of it, I can't think of the last time I had to skin any monkeys while on tour
