You can get one of the grabbing gadgets used for picking up things that are out of reach.

I would think the big, thick rubber gloves that go up to your elbow would provide enough protection from strikes

Chef's gloves. They are made to withstand knives and can get wet. They fit well and don't interfere with your ability to complete dexterous tasks.
