Leatherman Tire Tool
I was stuck on the side of the highway with a jack that could not work properly without the additional tool that let out the fluid and jacked up the truck to change the tire. I had nothing to use to operate the jack except my Leatherman Super Tool. I used my Leatherman to jack up my truck and let it down and it loosed the hydralic fluid so I could let the truck down and drive on my way.
I have had a Leatherman since the first Gulf War; it was a xmas present from my Lt. We all received one and since that day I have had a Leatherman. I have three now - a Wave and two Super Tools. I even bought a Leatherman for all the men in my family for xmas. I swear by them and wear mine every day. I have sent mine in 7 times and received a new one each and every time. Thank you, Leatherman Tool Group. Your tools are really the very best.
