This is one of the best knives I have ever had. I've been a S&W fan since the beginning, so when I saw this knife it was a no-brainer. Smoother and faster than most switchblades or other assisted-openers, and cheap enough that you won't worry about it if you need a knife you'll actually use! On thing to note though, is that you need to get THIS model, not the newer one. I bought a newer one and the new style safety is nowhere near as well designed. It uses a ball bearing that is pushed up into a slot on the blade by a pivot. The problem is that sometimes the ball bearing will come out of it's slot and move with the blade, locking up the knife.
