Y'all might find even more satisfaction in making your own flat
stamp... Not difficult to do.
Find some oil hardening drill rod or square stock at one of the
machine tool suppliers. Water hardening steel will work too. Using
needle files and rotary tools you'd be surprised at what you can do!
The material is cheap, and if you don't like the way your first,
