I started with a wire cup and will be progressing to 80 grit flap disc.
Will have to see if it needs more. Next project is a shovel.

Added 7 days later:

I am really grateful for Saltfork Craftsman and their swage block/Floor cones.

I went to their site this afternoon and was suprised to find this message.


NOTE: We have unexpectedly run out of swage blocks. Our foundry has been
purchased by a new corporation. It may be the middle to late August before
we have new castings. Please ... check back for updates."
