The Panther OTF knife is a double action (it opens and closes with the trigger) knife at an amazing price. Very similar in construction to some top line manufacturer's knives but at a fraction of the cost. The handle is extremely thin and narrow. I like this for carry. The blade is plenty long at 3.25". And it has a pocket clip. The blade comes out reasonably fast when triggered and I have triggered mine about 200+ times without any fails. It seems very solid. There is a little bit of play in the knife blade--it wiggles a little from side to side but not at all front to back. It is a great OTF knife, and for under $40 you would be hard pressed to find an out the front that is as good. If you prefer a wider blade, check out the lightning OTF from Taiwan.
