Everyone needs a little knife and a way to carry it, as well as display your AAC pride. The diminutive Piranha, made by Trango, clips to a key ring or a carabiner so you can easily take where you need to go. The blade is machined from surgical quality 440-C stainless with a serrated blade. The locking blade can be opened and closed with one hand but it's absolutely impossible to open when clipped to a normal carabiner. Bottle opener included.
