I think reading this thread, it seems that some peoples nerves in their hands are used to being shaken and stirred, "read possibly damaged already" to when some one who does some serious grinding work comes along, their hand nerves are still pretty much "all working and in one piece"
So you feel the vibrations that much more intense.
When I was in the ship building, many years ago, like 35 years ago, I had messed up hands for a few years.
But I think, taking time out of the heavy metal industry, does repair your hands to a degree.
I think now, if I picked up a 9 inch Makita, I would have segs and blisters before the day would be finished.
But now they are nice and smooth for other "applications" which beats the ass out of metal work any day of the week.
