I've had many multitools: Leatherman, SOG, Kershaw, etc. but the Leatherman Multitool OHT ($88) by far the best.
It's a bit weighty (as most multitools are) but this one has stood true through every scenario I have been able to expose it to: two tours overseas, buried in the sand; rescue swimming and diving in extreme search and rescue missions; and bushcraft survival.
It has every feature I could need in an every day life. I carry this tool more than my wallet, cell phone, even keys. I've modified a few little aspects on it just to suit personal desires, such as: replacing one tool for a phosphorus rod, using the lanyard hole for a self-made paracord lanyard including fishing line, weights, and hooks embedded, etc. But none of these mods interfere with the original tool itself.
I now work as a paramedic full time, as well as with at-risk youth for Outward Bound and I use this tool daily, usually multiple times. — Andrew Thomas
