Designed by Todd Rexford, this compact knife might be smaller than most, but it doesn't detract from it's exceptional qualities. From the astute design and finish to the convenience it provides, the Amplitude is one of the best pocket knives available. The blade is a reliable 2.5 inches and easily retracts back into the handle, due to the speed safe mechanism. Most users will find there is an air of sophistication with this tactical item, though it follows the traditional framework and structure of most folding knives. However, this one can be opened with one hand, giving a level of convenience that is definitely unmatched. Further, the steel handle is of great quality, aiding with grip and providing a stronger sense of durability. Those who purchase this specific knife will enjoy how it has been heat treated to add to strength and to ensure it remains in tip-top shape. Also, the specialized coatings of titanium carbo-nitride are extremely valuable to the overall structural appeal of this Kershaw blade. This is also easy to carry in any tactical case, or to add as an attachment to gear with the included pocket clip. Satisfaction is guaranteed!
