Sounds like a similar technique you have there. I'm sorry I can't answer your question since I have never seen any other agraffe cutter apart from the one I designed here back around 94-95, which was the drawing inserted in the post. I'd be interested to see Chris Robinson's design if anybody out there has an image. It's amazing how often the same problem gets similar answers. Does Pianotek have a web site, and if so, could someone send me the url? Thanks in advance.
