Chris D.wrote a review of Trango Piranha Knife on December 15, 2011
This is a great knife. It is the right size for stowing easily out of the way, with other gear or in the pocket. A word of caution to guys with big hands, this might not be the easiest knife to manipulate with one hand. Also it was a little hard to open and the lock did not always engage; however, a little bit of material removal made it easy to manipulate and locks in place easily. This is a great knife.
