Schrade's Viper OTF packs a lot of punch into a small amount of space. The double edged, black finish blade is made of 4034 stainless steel and has a scalloped design to the edge along with the Viper logo embossed in the middle. The aluminum handle has geometric designs to assist with grip and keep the knife from feeling too bulky or heavy in the hand. There is a sliding safety mechanism to prevent the blade from opening accidentally, and a glass breaker tip on the end of the handle makes this a great tool to keep in a car or 72-Hour kit.
