Stab Wound at a Knife Convention

[Knot]

Enjoyable character sketch, well executed.
My only real reservation is the title (which is great,
but I don't know that it works with the piece).
Minor points would be a couple of punctuation and
line length changes.  
As in:


The bartender

at the Burlap Stinkhole
is an old time freight train
with coal stained teeth
and an engine cough
that's rattled the screws
in the conductor's cabin.

He'll smooth your kinks
if you scratch his back[,]
with the right rake[.]
[B]ut don't touch his scabs
if you like looking in the mirror.

Mention my name
and he'll introduce you
to his dog's stomach.

I gave his sister a rash
penicillin won't touch.

I do think there's something missing (maybe only a line) between S3 and S4.

Best, Knot.
