I bought a bunch of used stuff when I first started this hobby and some tools came with the lot. My marvers and marble molds are graphite with threaded inserts in them. I have matching wooden handles that screw into the molds/marvers and are all interchangeable.
A guy that's been coming over my house to do some glasswork wants to know where he can get some. I can't contact the person I got them from because the PMs have been purged.
I'm attaching a pic of the tools. If you know where to get ones like these, please let me know so I can let him know.
Thanks,
