This was a striking (see note below) demonstration project during a basic blacksmith techniques class I helped teach over the last three Saturdays. One of the other instructors asked where he could buy a cutoff hardy tool? I said you don't need to buy one, we'll make it next week, and show our students another technique. A minute later our host found a jack-hammer bit for stock.
This was the first cutoff hardy tool I directed all the way through. Each tool we used I forged, fabricated, or assembled myself. It's a pretty cool experience to use tools you made to make other tools.
Note: two people a director holding the hot work piece and top tool, and a striker with a sledge hammer. This allows more/heavier work to be done with greater speed and accuracy. This project took just over 30 minutes including explanation to our students.
