The Kershaw Amplitude 3870 was designed by Todd Rexford. This knife is a neat piece to add to your collection of knives. The blade is made of 8Cr13MoV steel with a machine satin finish. It measures two and half inches long. The handle is made of 410 stainless steel with a titanium carbo-nitride coating which really makes this look good. The tip on this knife is excellent. The pocket clip can be changed from a tip up or tip down position， whichever you prefer. The Kershaw Amplitude opens with a Speed Safe mechanism by swiping the flipper on the spine.
