I made a knife from a Timken bearing made for some old piece of heavy equipment a couple of years ago, they call it 52100 steel I think, I had to learn a few things about heating and treating it, hardest part was getting the curves all straitened out, made a knife about 2” wide and 14’ long.
I have some pattern folded Damascus type of knives and if it comes to be I would like to build my own forge and hammer press, I just love Damascus knives. On Ebay you can get some really cheap ones from Ebay from Britain of all places, they may not have them legally but they sure make a lot, and I have one that isn’t some piece of cheap third world country crap, its really quite nice.
Just starting to forge knives myself. Lots of hammer in’s of late. Got most of my tools collected with tips from locals an folks here like Tet68. Still learning an wasting some railroad spikes in the process...:o)
You get a chance post a pic of that blade you posted about. If ya have time of course.
Stay safe...
That is very good steel for a knife. Marbles made their carbon steel knives out of that type of steel.
