I have a Zipper & have even carried it a few times. It's basically a prison shiv in a Kydex sheath. They're made from the "waste" created when 2 Woo knives are cut from the metal stock. It's an evil little penetrator, but there's no real edge & the grind angle is so steep that it's very hard if not almost impossible to put a working edge on them. It's not a "utility" knife at all. It's a purely purpose-driven design. (Now someone is going to make a liar out of me by putting a razor edge on one.) Any of Newts neck knives are a good choice- Hard to go wrong with the Executive NRG.
If weight/bulk are an issue, check the new Arclite by Camillus- good size/shape/weight/cost & more of a utility piece than the zipper. The Zipper is designed as a weapon.
