Almost every power tool I own is unsafe for my left handed son to operate. The guards, blades and how you stand over some of them all all designed for right handers.
Definitely would make one very, very attentive.

Yet when you design tools to be ambidextrous — think about the Colt CAR-4 rifle — you see an unusually high number of left-handed shots among soldiers & Marines. Didn’t used to be the case in earlier wars when bolt action rifles prevailed. I notice this constantly in photographs from Desert Storm, Operation Iraqi Freedom & Afghanistan. So there is a training component to this?
If tools & training are flexible enough to allow an individual to try it either way, suddenly the percentage of lefties for that activity goes way up.
Look at all the left-handed shots in Ice Hockey.
