Router (or handtools) to carve limestone?

["Simon Brown" <moonsong@zzzzzzzzzzzzzzz>]

Norman,

Yes. You can use sintered for marble, but not electroplated for granite.

Sintering means that diamonds and metal powder are placed in a mould and
heated to fuse them together (very durable, dry or wet), electroplating
means the diamonds are crusted onto the outside of a form (wet, light use
only).
