I carry a multi tool for nearly everything I do. Hunt, fish, camp, wheel,ect......
I've been through I can't tell ya how many over the past 25 or so years. I've come down to 1 particular model covering every need I have had, and some I haven't.
With a cost of $90 it's hard to swallow the initial investment, especially if you have 4 of them like I do!
Leatherman - Wave Multitool, Stainless Steel with Nylon Sheath

I can say that it has more useful tools than any other multi tool I've ever seen, it's still fairly compact, and light weight. It's never let me down, and I could literally survive the wilderness with nothing more than this tool if I needed to!
My only complaint with all of the Letterman brand knives & tools is that their knife blades don't hold an edge for long. It's still sharp, but doesn't stay razor sharp.
Do yourself a favor, go grab one, or a few. Throw them in the Jeep, your camping\fishing\hunting bags, and one in your go bad if you have such a thing!
