I'm not left handed, my DH is, but I am dyslexic and not only caused me problems in readying when I was young, I do think this is the reason that when putting a block together, I always seem to get one backwards. I always find it, but frustrating at times. I just thought it was really funny that both my cutters, which I have had since the 80's also, were on backwards. I've lost all my marbles, but still I think I've got everything screwed in right now.
