Newer Leathermans are much bulkier and heavier than the original PST which was light and compact. Several versions have tried to fill the void though.

For use in the back country, I think the Freestyle CX may hit a sweet spot. For those wanting a quality folder with a locking blade as a backup to their fixed blade, but also have a hard time leaving pliers behind, can now have both in one package, without needing screwdrivers and files (again, think back packing). A saw would be a nice inclusion though.

Having pliers to hold pots over a fire, take the lid off a dutch oven, or fix a pack in the back country, is really handy. Having a good locking blade available on it as well in such a light and relatively thin (for a multi-tool) package, is really nice.
