Magnet head

Ditto while grinding....goes without saying. Sometimes you gotta look right at the sparks from your grinder due to angle. I wear a welding helmet without the tinted glass down for that. Had an oxide chunk in my cornea, had to get driven to optometrist and she got it out with a Q-tip after an eyedrop was given to me to dull it. She rolled it against the direction she was going across the cornea so it would pick the piece and pull it out instead of pushing it or further planting it into the eye. Instant gratification! Sent her a Christmas card that year.
