Picked up some liquid nitrogen for heat treatment today; discovered that I've somehow lost vacuum in it -- it's evaporating significantly faster than usual. So, I'm finishing off a bunch of knives tonight so i can get heat treating done before the cold goes away.

anyone know where to get a dewar re-pumped around here?
