ive needed the leatherman more than a few times.. I've carried this large blue roll up pouch of wrenches, and its only really helped others now that i think about it... saved a couple harley guys in Colorado when I was living out there, guys bike broke down and he knew what was wrong with it, and I came by after an hour of them sitting there, and pulled over(Being a life long motocross racer I stop for bikes pulled over).
I told them I had wrenches for them, dropped them off, went back 12 miles into town and got us a 6 pack of New belgium and 3 paninis... we chilled for over an hour after they were done. They looked like road hardened bikers, most people would say they look "gnarly", but i have 2 friends in clubs like that and they are soft teddy bears...lol they offered me money, I said absolutely not, they offered me a gram of *******, I said, naw im good, but is it ok to shoot that hand cannon you are holstering?? they both laughed, he pulls it out like a cowboy in a dual, which scared the **** out of me for a split second, and handed it over... "safetys off"... it was a .45 acp that they carried because they would camp in the mountains when they would ride together.. i capped off 2 rounds at a nearby tree, they both yelled "unload it!!!" while drinking there beers, and I fired till it clicked... they both howled like wolves yelling at the moon... it was so surreal and awesome at the same time. I have at least 3 wrench stories but I won't clog the thread up.
i always carry 2 quarts of oil, a rand McNally map book, and extra cotter pins, jumper cables, 5 clif bars and a gallon of water is always in every vehicle 100% of the time.
