    How about a little more information so we know what the fuck you're
    talking about ?

    You can follow the link to a 16 year old posting. I don't understand why
    people dig up these zombies. When posters ask for some secret way to reshape steel without modern machinery I'm tempted to tell them to find a
    blacksmith.

    The PBS program on Ben Franklin showed forging the rounded end of an old fashioned key in a half-round die. A core box plane can cut a half round
    groove of any arbitrary diameter, to make a sand core for casting the iron
    die block. https://www.woodmagazine.com/woodworking-tools/hand/the-stanley-57-core-box-plane
