The Phantom Series Black OTF Tanto Knife can be quickly and easily deployed with the ambidextrous sliding button at a moment’s notice. Pushing forward on the button deploys the blade out the front of the handle and pressing backwards on the button retracts the blade back into the handle. The 3 9/10” stainless steel tanto blade is exceptional at both piercing and slicing due to its shape. The OTF has a black, metal alloy handle that is patterned for non-slip handling in any environment. The metal pocket clip is reversible and can be carried in the button back or button front positions. When clipped into the pocket it has a nice low profile “ride”. The end of the knife features a glass breaker pommel designed to shatter glass or break anything else you might need to in case of an emergency. When you purchase a Viper-Tec Knife, you get a manufacturer's lifetime warranty.
