makes sense - I always figured they were cut from a larger sheet, but then noticed the edge on my discs were too uniform, so figured they had to be "cast" in a round mold. - be nice to have some detail on the ingredients in the blue powder, and the temps used for the pressing.

I don't guess I have ever seen much less used any of the blue cutting disk.
I bought a red one some years ago because it was the only 14" disk in the store where I was the disk lasted forever the problem was it wouldn't cut it would glaze over on the edge then just turn the metal red the only way to make it cut was to bounce it up and down in the cut. Probably the only time in my life I was happy to see a disk grenade

YUP THATS WHAT i SAID.... THEY DONT CUT.THEY JUST LOAD UP.IVE NEVER FOUND ANY THING THEY WOULD CUT WITHOUT LOADING UP FAST. LIGHT PRESSURE OR HEAVY ALL THE SAME. AND YES BOUNCING DOES HELP....AS DOES SAILING THE DISC ACROSS INTO THE WOODS AND BUYING A REAL ONE.. THEY ARE GOOD AT BURNING UP CHOP SAWS....
