Sounds like pretty soon you'll be calling him "Such a quiet, nice man...Who'd have thought he was capable of such atrocities?"
(Just kidding)
I got to see some Civil War era medical instruments when I was little; scary. I guess a really good doctor could have your leg off in under three minutes, using what appeared to be a hacksaw...
That's pretty much like what it was...butchering saws are similar....Glad we live today instead of back then...
