I have a project where I need to cut a typical 5 point star shape (i.e. ★) out of brass sheet. The stars are small (~8mm across) and in high quantities. I was thinking of making a punch and die of the appropriate size but have stumbled on the best way to do this.
I'm stuck on how would I mill the sharp corners of the punch and dies - I was thinking possibly a gear cutter but the angle may be wrong? Would there be a better way to approach this entirely?
