Not absolutely sure if it is Carbon Steel. It's molded or sandwiched into the carbon steel. I put on the grinder and it made vary few sparks and probably mostly from the surrounding carbon steel. The hardened material appears to be molded into the steel by 1/2" X 1/2" strips side by side. The face side or wear side of the edge has been warn back to reveal the hardened material about 2/3 the way Back into the steel Thanks

I have been blacksmithing for about a Year. I received a Guillotine tool this today. I have some scrap 3/4" X 6" X 3' carbon steel plate that has a vary hard 1/2" X 1/2" steel strip molded into length of one edge that I tried to cut with a chop saw. It was a scrapped ware plat that came off a modern road grinder. I was able to cut down to the hardened edge then I about wore out the abrasive disk trying to get through the hardened edge to make a fuller for the Guillotine. Do you know if there is a chop saw cutting disk made that will cut through the hardened 1/2" of the plate or would I have to torch it? I also have a Keller power hacksaw but I don't believe the Blade will cut it ether (haven't tried it). I also use a coal forge but don't want to go through the re-tempering or even if it would be possible. Any suggestions? Thanks much. tom
