Leatherman has introduced the Skeletool and skeletool CX:

pocket clip – so it can be used with or without a sheath.

The Skeletool CX has carbon-fiber handles; Erik Sofge, in his Popular Mechanics review (link below) says that it’s got a particularly comfortable grip – no small asset for a tool that, almost by definition, one uses in less-than-ideal conditions. The CX also has some attachable bits stored inside the tool. (I’m not entirely sure how they both end up the same weight – this may be the result of my misreading the specs )
