Scallops
Good knife. Had one until a couple of months ago.
The Zing's wavy scalloped blade surface is especially useful if you're using it to cut stuff that would normally stick to the blade and add friction.
For example, a block of cheese will act like a vise on a smooth-sided knife. A cucumber or potato will leave slices stuck to the sides of a smooth-sided knife. The wavy/ridged/scalloped sides will shed things like that.
I recently gave mine (orange handle) to my son in law, and he's liking it.
BTW, the G-10 handles can be just a little rough on the pants, so we did a fingernail polish treatment to mitigate that.
