Try a wood carving store (Woodcraft). They have special gloves for those guys who become intimate with a very sharp knife and a block of wood. I have one, but it doesn't come close to my quilting table. I am just careful with a rotary cutter and haven't felt like it was even close to jumping over the edge of my ruler.
One thing to keep in mind is when cutting, put yourself into a zone where all attention is on the task at hand. If you can't and have frequent distractions, internal or external... do something else.
