Thanks folks!
Razor... The billet was forged by stacking: 1/4" wrought iron plate, pure nickel foil, 1080, pure nickel foil, 1/4" wrought iron plate. The surfaces were all ground clean and flat, stacked, placed in a vice to shut it all tight, and then all seams welded with a Craftsman 110V wirefeed welder. I weld up all seams to prevent any oxygen from getting in there and scaling surfaces. Nickel can be tricky to forge weld and any scale can cause failure. I then weld a rebar handle onto the billet, soak it at a high welding heat and hammer down to a 1/4" billet. I can usually forge the tip down without delamination, but I don't recommend it for your first time! Better off treating it as a stock removal project once your drawing out is done. When drawing out, I count hammer blows and make sure that each side is forged the same way otherwise your core can get very wonky.
