After a long, sweaty afternoon, I managed to make a functional pair of flat tongs! As usual, practice is more difficult then reading about it on the Internet. First I made two mirror images, so they didn't fit together. Somewhere I got rotating left and right mixed up. Cut it of and repeat. I had some trouble to get the jaws and the bolster into the right shape. This is rather critical, otherwise things don't fit! Drawing out the reins was the most difficult part of the job. Somehow the theory didn't work, hammering over the horn of my anvil didn't change much in the thickness of the bar. And last but not least I was strugling with the rivet. Getting a glowing hot small piece of steel in two tight holes at the same time and letting it protrude equally on both side, ain't easy. But in the end, I did manage to make a real working pair of tongs. A few blisters in my hammer hand is a small price to pay for a price like that. BTW, i used the instructions from Abana: https://www.abana.org/resources/chf.shtml
