The SwissTool multi-tool includes
a simple fold-out can opener that is built into one of the plier arms.
Because the Swisstool has a positive blade lock for all
of its blades, the can opener and small screwdriver on the SwissTool
are safer to use than the ones on regular Swiss Army knives.
Uses: The SwissTool can opener is not the world's fastest can opener,
but it does a decent job for occasional use. The trick is
to puncture the can with the sharp part of the blade, and then move
forward by about 6 mm / 1/4" and slice a bit more of the can with the sharp, curved part.
WARNING: The can opener tends to leave a jagged edge on the can, so
use caution!
