© Jeff Crowner 2009The Rupa Rupa Jungle Blade is a design I came up with a few years ago specifically for jungle applications in the Amazon basin. There are few of these being used in the Amazon right now as I write this post. This particular one was made for a serious wilderness survival instructor for serious use. The blade is a CPM 3V steel with TeroTuf handles made by CIP composites in Eugene Oregon. I've made many other Rupa Rupas in a variety of other steels, but this here is a race horse of a knife with the CPM 3V. Conceived and constructed solely for survival personnel where their tools mean the difference between life and death. One can make many shelters, perform basic defensive techniques and process a lot of game with this blade and never worry about chip out and breakage. All the Rupas have a convex grind down to the edge and are Cryo treated with my heat treats.
