Smith & Wesson Knives. The famous gun manufacturer has designed their own line of knives with the same quality and attention as the guns they've made for years. If you demand the best, then these are the knives for you. All Smith & Wesson knives have a lifetime warranty. Designed by Master Knifemaker Rocky Moser, the Power Glide knife was named "Blade" magazine's International Best Designed Knife of 2002. Black 440 steel tanto 3.70" blade (9-1/2" total length when open), Zytel-coated aluminum handle and pocket clip. This new updated version has many refinements, including smoother lever action and a more utilitarian, modern design. To open the knife, split the handles, pull them apart - the gear action moves the blade forward. Halfway apart, push the handles back together to finish the opening process. The blade cannot be drawn back until the handles are opened again. To close, simply open handles and reverse the opening process.
