Here is a one piece tool i can really get behind:
http://www.oldfamiliarcombcompany.com/Sure.. it doesn't drive screws or turn a nut.. but that's why I have a SAK or MT. I wouldn't pry with it, but then I prefer a mini pry bar for that anyway.
No, this one piece design does two things only, and it does them both well:
1. Comb hair
2. Open beer
Oh, it has a hole for a lanyard. Leatherman counts that as a function, don't they?
Anyway, I got mine today and I love it. Thick, polished, but not too polished. It looks like something my Grandad woulda had next to his old Marble's match case. One of these, a white handkerchief, a worn leather wallet, and a silver dollar.
The only way you could improve it would be to attach either a switchblade, or a pair of breasts. Or both.
So my hair looks kempt, and I'm well into some good suds.. Let my multitool handle the rest.
