I might have held a defective one, but the one I looked at @ Wal-Mart had a blade that didn't lay flush with the handle when closed. There was a very small gap, which could lead to you getting cut. The KISS that I have seen didn't have this problem. Take a look at the Gerber if you can, and see if they all have the potential problem I mentioned.

Edited to add: Just be careful with either one, as the exposed lock can become disengaged with a tight grip, especially if you rotate the knife while cutting. It's a light duty knife, and should work fine in that role.
