A hand cutter with a retractable blade guard (30) providing an unimpaired view of the blade (20), when it is placed on the object. The blade guard is unlocked and retracted by a trigger mechanism, which is activated by closing the hand around the cutter handle (10). The blade guard remains in the retracted position until the trigger (62) is released or a relocking mechanism is activated by putting the blade to use by cutting the object. |
