I know there's another company that others use. I can't remember the name, though. The stencils last for a long time. I'm probably getting around 8 knives per stencil before I need to move to the next one.
I also have a steel stamps makers mark, but if you are planning on using a hot punch technique with a hammer Id suggest tempering back the striking side of the stamp. Early on mine threw out a large chip off the striking side. But their customer service about the issue was fantastic they sent me a new one right awayill check them out, how are their prices? yeah i was wondering about the sizing with a stamp... im going to print some scale models to see what is too small
ill definitely have to try that.
