My inquiring mind just asked me why the preponderance of threaded
fasteners, jar lids and stuff have right hand threads.

Most people are right-handed. More torque from a screwdriver tightening
in
that direction.

Depends if you hold the screw driver with the blade end away from the pinky
finger,
that would give more torque un-screwing. If the blade faces away from the
thumb, then
you have more torque tighting. Give it a try.

Sheesh Jeff, I must have more time on my hands then you actually trying this
out. G
