Thread: Iwasaki???

Usually when you mass produce stuff you have the HT temps nailed down. all are the same, but when its 1 at a time and coal/gas furnace it gets whatever you get imo. personally I would not trust any maker that uses gas or coal furncace because i very well know if your'e 10-20 deg C off its not getting hardened to its full potential. And pretty anyone with access to the tt-table (time-temperature) for that steel will know this. I regard all coal/gas forgers/heat treaters as hacks but thats just me. But I can back this up with real science. so can you.

I'm willing to bet that a uddeholm aeb-l hardened to 60-62hrc blade will be more edgeholding than any "swedish steel"(whatever that may be)/tamahagane jap in the world. But hey wtf do I know. But I have read the good books though.
