Review on Innovative Bench Pin Slot Inches BPN 103 08: Your Ultimate Workbench Accessory by Jerimiah Augustine

I have a new jeweler's bench from PMC. it's high Nice. Unfortunately, the mounting part of this pen is so tiny that it was literally fun to get it to stop. Unfortunately this seems to be a standard size so I am currently looking for a needle that is not too small and has grooves for small cuts. After days of searching I'm not sure if there is such a thing.
