If you need a cheap knife because you lose them like I do or need one at every work station like Dennis, Fastenal has a bunch of clearance. Since they're on clearance, check inventory before you run out $2.79-4.49 prices.

Wow - those are cheap. I carry a benchmade and those in the link look exactly like mine. My benchmade cost
$ 100.00 and I did loose it once - man that hurt. The new benchmades aren't quite up to the standards of the one I had that was about 20 years old.
