I worked at a large butcher shop as a teen. I calculated that for the career-guys there, they averaged one lost finger for every 5 years of work.
It was a real motivation to further my education.
I put in equipment in a plant like that where you could estimate tenure by missing digits. I guess if you lose all 10 they give you a gold watch and retire you.
The old timer brothers at the butcher shop where I worked as a teen were virtuosos with a knife. Between the two of them they had 75 years of experience and were only each missing the tip of one finger.
