Allan,

I'm not left handed but I'll attempt to explain. Pick up a pair of scissors. Notice that the blade your thumb operates is away from your palm. Notice that a normal cutting motion tends to push the blades against each other. Now switch to your left hand. Notice that the same motion tends to push the blades away from each other. This is easier to see with a pair that is a little loose. Left handed scissors are the opposite.

Ok lefty's did I get it right?
