Hi Alvin, long time no talk to. I did a sparkem test. Look alot like
L-6(band saw steel) more sparks that O-1, but I'm very knowledgeable
about all this high teck stuff. I is a woodworker (or that is what I
tell people). I just grind out a few knives for woodcarvers and wood
butchers like me. These chiny masonry nails seem to hold a good edge
on the small chisels that I make from them.
