The difference in price to acquire the various raw steels for ONE blade is not all that different, say approx $4 to $10 range.

So double the retail price (say $100 jumping to $200) seems a little bit of a gouge to me. Once you have the raw steel, the rest of the process to completion is not really different except for a heat treat schedule difference.
But price is set more by what the customers will pay, not necessarily fair mark up.
Just my thoughts and opinions.
