The best home treatment for deep cuts is superglue, it will save you a trip to get stitches if they were needed too.
The funny part was it did not hurt that bad! (and it was a 7 shave Derby)
I got it to stop really fast with this powder called QR (quick relief). My daughter used to have nosebleeds that we could not seem to get stopped. Purchased this but never used it. I guess this stuff was 4-5 years old. It worked like a charm.
QR also has a formulation for cuts, lacerations. It is great, I know I will be buying more, plus some steri-strips. You know, I had changed that razor half a dozen times, with NO problems.
That was your razor Rich! But if I had cut my thumb OFF, I still would not have gotten rid of it!!
