CobraTec has some amazing quality OTF (out the front) knives at affordable prices.  An OTF knife is one that has a blade stored inside the handle.  The blade is deployed by a switch and retracted by that same switch and is a perfect every day carry knife.  CobraTec knives have a limited lifetime warranty so you can rest assured you are purchasing a quality knife.
