OUCH!! Back in the days when I was doing lots of MMA, I faced my blocks
with a Buehler metalurgical saw. I then put the blocks in a vice grip and
trimmed off the excess plastic around the tissue with a coping saw. I took
a metal file and filed the edges so they were slightly rounded and clean of
any hangers-on. This method does not require kevlar gloves.
