Sorry to hear that. After 38 years of working in machine shops I'm thankful to have all my fingers even though one of them doesn't have much feeling on the end.
My buddy George is a butcher at Pathmark. Years ago he severed his left thumb, while cutting a frozen turkey on the band saw. Saw caught the metal band that holds the legs together, and jerked his thumb into the blade. He is missing 3/4 of that thumb. I seen him a couple of months ago with his right hand all bandaged up. He cut his right thumb off doing the same thing, this time they could reattach it. I think he should find a new profession.
