Featuring a unique design for quick and easy operation, the Glaive Automatic Knife from Telum Tactical can be fully opened with the push of a button to release its coil spring. The bottom also works as the locking mechanism when open to hold the blade securely in the open position. A slide safety lock on the side can be used to lock the button in the open or closed positions. The Glaive measures 5 inches when closed and features a 4-inch D2 satin stone-washed clip blade with a hollow grind and a sleek, contoured G10 handle. An extra-long pocket clip sports a tip-up design for added security. MSRP: $74.99. Contact: www.telumtactical.com
