To answer some of the questions...
I am ambidextrous, so I really don't have a dominant hand. I can cut with a cutter set up either way.
I cut into the index finger of my left hand last year and still don't have feeling in the edge that was cut. This morning, I noticed that the right hand index finger (cut Sunday) is actually looking really good with tons of new skin growing. Guess the doctor was right: cutting it completely off is better LOL
Thanks for all of the input. I will check out all of the ruler guides and the gloves and see what seems to "fit."
