Sometimes you just want your knife opened quickly and there is really no quicker way to flip open a blade than with a Wave system.
Designed by Ernest Emerson, the Wave system is a patented feature that pulls open the knife by means of a hook on the blade as the knife is drawn from the pocket.
The Spyderco P'Kal utilizes a small metal stud in the back of the blade.
The system works best on fatigues or jeans. Don't try it on dress slacks. It takes a little practice and you are cautioned to stay clear of others as the blade is wicked sharp and the movement could cut those nearby. So practice by yourself before you “go live.”
You can, of course, pull the knife without using the Wave feature … but what fun is that?
As for the knife, not withstanding the Wave feature, it is pure Spyderco from end to end. It is built tough, razor-sharp and fits the hand like someone really thought about the design. The blade shape is perfect for defense and also for very handy daily chores. The G-10 handles are tough, thin and light and the belt/pocket clip is tough enough for anyone.
