I wear gloves too when hogging metal away. When they wear through I wrap masking tape around the holes. However, I do not use a tool rest which might allow a space for a glove to be caught. I don't know. I have always ground my blades free hand, even while hollow grinding. And yes, I can feel what I'm doing while grinding. You learn to feel through the gloves. More so than through a push stick. To say never use gloves is a far stretch, but you do need to use common sense as to when, where, and how. In 32 years of grinding with my Olympic Square Wheel grinder, I have never had even a hint of problem with wearing gloves, except on occassion my masking tape patch work has caught fire. Just a tad bit. If using a tool rest, grinding jigs, ect. it might be best to go bare handed, but if grinding on an open wheel, you would have to purposely stick your hand between the wheel and belt, and if you're that stupid, you should not be making knives.
