This Socom Elite Forces Urban Camo Combat Troodon Knife is a tool used by special operators around the world and features a 440c Stainless Steel blade with a two tone matte black finish. The Double Edge Blade can be quickly deployed with the ambidextrous sliding button. Pushing forward on the button deploys the blade and pressing backwards on the button retracts the blade back into the handle where it is ready again to be deployed at a moments notice. The 3.9″ Double Edge blade comes with an aggressive partially serrated edge giving you tearing and cutting power making it a great all purpose blade. The Tanto blade is exceptional at both piercing and slicing due to its angular shape and tapered spine which creates a strong point. The Zinc Alloy is “rubberized” and 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. All Knives have a safety feature that will not allow the blade to fully deploy if anything is obstructing it’s path. The blade will then need to be reset by pulling the blade all the way into its locking position making it again fully functional.otal Length : 24cm / 9.4in Blade Length : 10cm / 3.9in Blade Thickness : 0.3cm / .11in Blade Width: 2.8cm / .11in Blade Material: 440C Stainless Steel Handle : Zinc Alloy Hardness : 58HRC ** Gross Weight : 260g / 9.17oz Total Weight : 430g / 15.16oz (NOTE: All Socom Elite Forces Knives are assembled and tested in the USA.
