Microtech Ultratech Signature Series OTF Automatic Knife

This Microtech Ultratech Signature Series OTF Automatic Knife is a fully automatic knife with a double action out the front mechanism, which means the thumb slide deploys the blade and retracts it as well. It is the leading example for OTF knives. The Ultratech features a smooth, contoured handle design that makes it more comfortable during use. The Signature Series handle is made of aluminum and comes in a variety of colors and hardware finishes. The blade is available in several unique styles and finishes.
