NEW ITEM: Pneumatic Scribe
For those of us who can write cursive (handwriting), it is fun!
The tip is carbide and sharp enough for quartz. It is very powerful and you can adjust the speed.
I use it for my signature on a sculptures.
It is a VERY SHARP CARBIDE point, not a flat chisel.
We have had several requests for this kind of tool.
Try it as an etcher on glass or granite!
