The cost of a piece of metal in your eye.
I Have done it also. I was cutting 2 1/2" pipe, and also had a brand new face shield that was preiviously given to me for the same reason i am talking about ( metal shot into my eye before). I was cutting and couldnt see so well if i was on the line i marked. I took the shield off( kind that looks like a hard hat with plastic shield upfront), and a small piece that looked exactly like an arrow shot straight into my left eye. I was quickly blinded, but somehow found my way into the house over pipes and steps. I cried like hell lol i was scared as well. I no longer had insurance, which scared me also. I know i should have went to the hospital, but i had no job, no money. I got a very strong magnet( the kind they put in a cows mouth) and hoped it would stick. Sure enough it caught the metal and i washed my eye later.. To this day my eyesight isnt so great. I am only 19 years old. And have went through 3 eye surgeries(before that) one for one piece of metal, and 2 for my eyelid falling from loss of muscle/nerve.
