now I am confused more

Bill Tindall, E.Tn.
What I'm doing would be easy for someone with a forge and an anvil to duplicate.

There's no commercial value in it as 52100 is a forging steel and not a cut and shape steel.

I'm skeptical either of these statements is true if we add "boutique" before commercial.

From what I have read about this steel, and your reports, you seem to have found a good chisel steel. Exploring how to fabricate it into a chisel I can follow. The results would be judged attractive and desirable by all. Anyone that has used one of your chisels will be smitten by how nice it feels and the hand.

Its the heat treating I don't get. With no stake in the ground to know where you are at, and no details of how you got there, any result on performance as it relates to the steel is hard to interpret. Add the fact that you sharpen with complex bevels known to have an overwhelming affect on folding/ chipping and I have no idea how this chisel steel compares to whatever.

I thought you were filing these shapes and forge welding the bolster? I may not know the details what you are doing that results in an attractive chisel that is sure nice in the hands. For me the details either were not provided or got lost in the description of the journey to get there.

We certainly don't know enough about the critical step of heat treating that someone could duplicate. More important what are you doing as it relates to what must be a wealth of information of how to heat treat this steel to achieve the performance it is capable of delivering? If nothing else determine from data on this steel what heat treat should optimize hardness and toughness, send some chisels out to a reliable heat treater (there must be numerous in a stones throw of where you live in the Steel City) and get a stake in the ground to compare your results to.

Heat treating is not easy to do reproducibly or to reach a target. I watch Forged in Fire occasionally. I am amazed at the steel failures these professionals suffer at the hands of their shade tree heat treating. For a time I did temperature sensitive chemical reaction rates in ovens . Determining what the temperature is and how it varies at any spot in an oven showed me that a heat treat oven that produces reproducible results at a target is a marvel of technology.
