Body repair man, fabricator

My uncle used to have a race car fabrication shop and when I was a little boy he would give me all of his tungstens to sharpen i would then take them over to the sanding wheel and put a nice sharp point on them while he was welding and would just stand by and as he would need a new one he would hand me the old ones to sharpen.

This was done because he would be in a very awkward hard to get in position and would not want to have to get out.

From my experience I don't see that it is super critical especially in an environment like we were working in a race car fab shop.
