I guess my oldest two blades are the "Negrito Hunting Bolo"(Bowie with a 9 1/2 blade) made in the Philippines from a leaf spring and ONLY the springs temper. And a 6 inch hunter that a guy I knew (he died about 12 years ago and was in his 60's) made in high school shop class from an old disc blade.
