Which tool is more easily used by a right handed person, than by a left handed?

screwdriver
hand saw
electric drill
hammer
The reason for the clock­wise ori­en­ta­tion of most screws and bolts is that supina­tion of the arm, which is used by a right-hand­ed person to turn a screw clock­wise, is gen­er­al­ly stronger than prona­tion; while screwing is gen­er­al­ly done more often than un­screw­ing.
