Subject: tungsten for granite working

I use tungsten for roughing out and for the larger planes of moldings,
stone cutting (banker masonry), but fire tempered steel for everything
else; so probably 90% of the time I'm using tempered steel. (this is with
Indiana or Kansas limestone; with softer limestones, like Texas Cream, I'll
rarely use carbide unless I run into a shell that I'm cautious about
popping out... for the brits in this discussion, Indiana limestone is very
much like Portland stone, Texas Cream is like Bath stone).

In marble I do a larger percentage of the work with carbide.
