BOY - that sounds like a world of FUN. I've never cut anything completely off. Not even the smallest hunk of hide. But, BROTHER, do I ever have the scars from deep cuts. The worst being - chainsaw to the heal of my thumb.
I can tell you - it hurt like nothing I had previously experienced. Got my pants down fast enough so that I didn't crap myself. But it was close.
I thought it would quit bleeding pretty soon - not the case. So I squeezed it close and held it that way with small bandages. This was a whole lot of fun because blood was running everywhere. Wrapped it in the cleanest shop towel available and high tailed it home on the tractor.
At home - cleaned it up more - more small bandages. Then I got out the little bottle of Liquid Bandage. That stung like mad but pretty soon it stopped the bleeding.
Regained what composure I had remaining - got in my vehicle and drove to the local Medical Center. Of course - first was a great big Tetanus shot.
They stitched it shut and now I have a very fine scar from the heal, half way up the thumb.
Strange how you remember the pretty nurse. I remember the fellow who worked on my thumb. He could have been a pro wrestler.
