KaiPLwrote a review of Trango Piranha Knife on May 23, 2015
Familiarity: I've put it through the wringer
I bought this knife because I wanted a small, light knife I could take with me for climbing. I bought it, stuck it on a carabiner, and pretty much forgot about it, until it poked me when climbing. The rivet that attaches the blade to the body had loosened up, and the blade just fell open. It's not supposed to be able to open when it's attached to a carabiner, but it does. Having an open knife attached to my harness isn't a great situation for climbing. Got rid of this piece of junk knife, and replaced it with a (1st gen) Petzl Spatha. A bit bigger, but much better quality.
