Just been watching this video and was wondering what the guy is
resting his sheet of glass on, look like some form of neoprene/rubber
pad. I think I can make out the letters axler on one of them, but a
Google search (with wildcards) does not produce any satisfactory
results. Any suggestions as to what they are/ I am hoping to set up a
sharpening bench and like the idea of the reversible sheet of glass. I
could use some neoprene offcuts.
