I've considered that, but I think I'd have to do something similar to color case hardening just to add some carbon, but getting that right on the first pass in the Prince Albert can full of crushed bone is beyond my talent. I can, or could well back in the past, do anything you want with the puddle of an oxy/acet torch using coat hangers (paint optional) for rod just by adjusting the flame. Short, "hard" flame burns carbon out, leaving a soft weld, a long feathered "soft" flame can add several percent of carbon to the puddle if that feather is touching the puddle. But this should be done at a lower temp I'd think, and for an extended time frame to get good penetration, adding 1 percent throughout w/o getting brittle. You still need to be able to burnish the j hook edge without chipping it. No clue if as shipped A2 would be soft enough to work. I should, when I find that round tuit, investigate that possibility. A thicker, stiffer blade would also be an asset, 1/16" is pretty puny. The clamp I think could hold 1/8" material.
