I always use the glove. Always. In college I cut a slice off the side of my thumb with an xacto blade. The size of a dime and as thick as a nickel. 9 stitches, and an emergency room bill for an uninsured college student. It took years for the finger print to grow back and the numbness to go away. The reason I wear the glove, is that my minds eye saw that my thumb was in the line of cutting but I didn't stop the cut till I finished the cut and my thumb. Luckily, I saved the piece of thumb before it went down the drain or it would have been harder to heal. Wear the glove.
