The Medium VF-1 Series Double Edge OTF Knife is ready to be deployed at a moment’s notice and can be quickly deployed with the ambidextrous sliding button. The knife has a 3 1/4” stainless steel blade with a two-tone finish and it is exceptional at both piercing and slicing due to its shape. 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 tough, metal alloy handle 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
