Here is a tool I made from a piece of sheet metal and a length of rebar.
It's a leather working tool called a "Stitch spacer" or a "Pricking wheel".

To use this tool you run it across a piece of leather and the marks it make will be where you put your holes.



I will need to find something to act as a handle for the new one.

The most difficult part to make was star wheel. Lots of angles to map out on a piece of sheet metal and a lot of of filing. For some reason I can only map out 8 pointed stars, however in this one I managed to make it out of center, but luckily it still works the way it should.
