I have a big plastic one but it's a PITA to use on these small blanks. So I was searching for one that would work. I found 2. One was a small keychain but the shipping was as much as the tool. The other was the woodpecker which was $30. Plus the shipping. I had a friend draw what I wanted in CAD, a skill I don't have, then I had it 3D printed. Below is a picture of the result.
