i have a leatherman charge AL, which is the same as a 'wave' model,
except that it has more high grade blade steel on the knife blades (154cm vs 420hc in the wave)
its a great tool, but due to it being rather heavy it is not very likely to be on your person at all times.
anyways i would like to point out that the wave and charge come with a bit driver that takes
leathermans proprietary flat bits, but you can get this same capability in a bit holder that
can be attached to the phillips head screwdriver in the juice models.
personally i have the leatherman on my desk, but for carrying around i much prefer the victorinox swiss army knives.
i like the form factor much better for carrying, and the scissors are much better then on leathermans. (though the scissors in the juice
are significantly larger) i use the scissors all the time to cut leads of trough hole components and strip wire and things like that.
