|The Can-Opener is a tool with a lot of history. |
The can-opener appeared on the first Swiss Army Knife in 1891. The original design was dedicated to the task of opening cans, however the contemporary version (patented 1951) has the addition of a small slotted screwdriver that is shaped and also intended for use with Phillips screws. The width of the screw driver end is roughly 3mm. The current tool has a hardness of RC 52.
The blade on the contemporary version is more versatile and has been used with wire shielding, snap-back watch cases, and other small blade short cut duties where the shorter tool length provides better control.
The Can-opener tool now has a cousin, the Combo Tool.
