The cost of a tungsten-carbide-tipped lettering chisel is about £15, and of
a suitable dummy about £25. Not much cost, but quite a bit of skill needed.

Hi dialist fellows!
I'm considering to make a sundial with marble. Does anyone have some tips in
how to engrave this type os material? I've already manually engraved slate with
nails of different diameters, but when I try the same process with marble I do
not get neat lines.
What I'm looking
Very fine lines can be etched with an abrasive blaster. Silicon carbide
is the best blasting material, but aluminum oxide (less expensive) also
works well. I hire a sign maker to blast the granite (and occasionally
marble) stones for my Sawyer Equant sundials. The lines are about .040
wide
