I've done a ton of reading and cannot seem to get a direct answer to this question:
Leaving the scales aside, and considering the same type material, what is the difference between a $100 Dovo, $250 Boker, $300 Thiers-Issard etc...etc...I am only talking about the blade. I understand scales can add quite a bit to the cost, but I'm just asking about the steel.

Thanks for the patience.
