Trango Shark Nut Tool - The Shark Nut Tool by Trango is an incredibly versatile nut tool and knife in one! The Shark combines two useful and common climbing tools into one, a stainless steel nut tool, and a razor-sharp locking knife. The serrated blade is machined from surgical quality 440-C stainless steel. While the locking blade can be opened and closed with one hand, it's absolutely impossible to open when clipped to a carabiner. The Shark uses a side-lock mechanism to hold the blade in place once it's open. To close the blade, gently push the side locking mechanism out of the way of the blade. Perfect for sawing through the wad of slings that's keeping you from clipping that fixed pin. Whether you are cleaning a pitch or prepping your dinner, make sure you have the Shark Nut Tool by Trango.
