I would think you could make something similar with a couple of nail sets.

I have polished and shaped pins and washers with a short piece of Bamboo with a divot on the end, the size of the finished pin I am trying to replicate. Dab on some .5 diamond paste and do small taps with the drill press adding diamond and tapping until you get where you want, final polish with a dab of Maas on the Bamboo.

JFK, make sure to taper your pin holes to prevent cracking.
