I was working with a 3/4" x 100' sewer snake on sunday and I nearly tore my finger off after my glove got caught up in one of the grooves. My glove wrapped around my finger so tight, it created a crevasse-like channel along the base of my index finger which eventually puffed out to normal round again. It squeezed so hard that had the glove actually cut my skin, it probably would've sliced right to the bone.
Things I've learned from this experience:
A. Plumber's are wonderfully talented people
B. I love my fingers
C. I'm an idiot.
