Hopefully you'd never have to use it, but should the need arise, you'll certainly be glad to have the Leatherman Raptor ($TBA) at hand. Developed for uniformed medics, this scissor-like multi-tool features 420HC stainless steel shears, a strap cutter, a carbide glass breaker, a ring cutter, a ruler, and an oxygen tank wrench. Available May 2013.
Like to carry your keys on a carabiner? Upgrade from the climbing gear to something more refined... like the Keysquare ($36). Designed specifically for carrying your keys, it's cut and machined from a solid block of stainless steel and hand finished for durability. While it sports a long slit for attaching to a belt loop, it's still small enough to easily slide into a pocket, and like any good piece of metal, it also doubles as a bottle opener.
