Don't trust your life to it....
This thing seems like the ticket. Small size, good features, and Leatherman normally makes a really nice product.
Mine however basically rusted itself shut. Its not like I left it outside in the rain for a winter. It was in a slightly damp backpack pocket for a day or two. The pliers was nearly welded immobile, and now the small tools won't open unless I break a fingernail off prying at them, or use another tool. Weak sauce.
Tools like this are essential! So nice to have when they work. But maybe try one that is more corrosion resistant, and if you do get this on be sure to be dilligent with keeping it dry and lubricated.
