I'd say Mr Demmer is a good judge of character. OP didn't get what he was looking for here, look how he reacted.
You choose a maker because you trust him to make a knife........not to tell him how to make it.

OP you should listen to this, generally you do not pick a maker and tell them how to do their processes. Each makers have their own process and what works for one will not work for another.
I would like to add this though, heat treating for most makers is not an exact science, there are so many variables that you asking for a specific heat treat is not reasonable. This maker has the blank cut so he isn't making the steel, steels from different places have different characteristics even if they are named the same steel. The processes, seat treat and grinding cause a lot of variation, not to mention if they maker even has testing equipment. So guys that get so infatuatated with a hrc of 60 vs 61 on a certain steel.... But fail to realize the hardness tester used (if a maker even has one, and that's if tent do their own ht) is like +\- 2........
A little knowledge is a dangerous thing.
I think this was not an agreeable project and the best is to have refunded you even if that cost him some money. My generally policy is to hold the money in an account and I don't touch it till after the 1 month trial period I give to my customers. I do this because I had an issue where after I completed the knife and the customer was happy, he ran into serious money problems. The knife was $4k and I used that money to buy some more very expensive equipment, but as I said I have a 1 month return period so I refunded him after knife arrived. Luckily he knife was sold within minutes of posting. This taught me a lesson not to spend the money until it's all settled.
The same customer contacted me and asked to have another build, I politely said no because my books are closed forever.
I think there are times when a maker just has to say no and cancel an order, but the refund part is very tricky because of the material cost and labor. I think the maker handled this correct in wanting to send the blank to the OP.
There is no need to get crazy and fighting with posters in here, be respectful that they have a difference of opinion.
