    The modern type are available on line. The bay often has them as do some of the Dovo suppliers. Just a fancy headed nail and a shaped washer for the other side.

    Thanks Richard. Maybe I was unclear. I have not been successful in duplicating the original Geneva/Genco pins after I have unpinned a Geneva blade. IMHO Dovo pins look nothing like the old collarless Geneva/Genco pins. Maybe I could chuck up the Dovo pin and reshape the head.
    Regards,

    I sometimes use the brass Escutcheon Pins from a hardware store. The shank is often 1/16th inch diameter.

    Many hardware stores have them. I also use Brass Finishing nails and pound the head into shape with a ball pien hammer with the nail in a 1/16th" hole in a bar of steel.
    I have used a small collet in a dremel many times as a lathe.
    I use the supplied arbor that has a screw to hold the washer to make a tiny one.

    I have tried. I can get a good one with the pin chucked-up in a drill chuck. I seem to flatten them out anyway attempting the other side. Might try a divot block someday!
    I am certain they did those with some sort of press. "Ker-Chunk!"

    No, Pixel! look at them! I piece pin pinned with a perfect dome from the factory. Both sides! The factory Gencos and the like, had to be pinned by a press. They look and work excellent. Just how to replicate? IMO!

    I would think a rivet set would do it. Kind if like a doming block only on the end of a punch.

    In this case you would only use the dome part and not the holes for pressing the material to rivet.

    And you may have to make a special one for that particular pin ?

    10Pups got it right.
    It takes a few tries (or math) to get the pin length correct, but after that you use a doming tool.
    After you get a good dome going, you can use a vise to do the final lock down.

    You can make your own doming tool using scrap rebar, a drill bit, and a dremel round head carbide cutter.

    I think they used a tool called a head spinner. Commonly used for finishing the pins on pocket knives, used to be available from Jantz. You put them in a drill press with a corresponding rest underneath.
