For instance I wouldn't expect 13C26 to have the same edge stability as 12C27M at very acute angles so might run a slightly more obtuse geometry...
13C26 has inhernetly greater edge stability than 12C27M not less, so it should offer greater performance at more acute angles.
... you would like to see a 13C26 blade ground very thin and run full hard.
Yes, depending on the knife it would be full deep hollow or high flat. The heat treatment would be oil+cold for maximum as quenched hardness and tempered low to maximize edge stability.
It makes no sense to use it in thick profiles because in such a grind you don't need edge stability in the steel because it is inherent in the grind. Thus you would use a higher carbide steel and get the benefits of more wear resistance.
The only reason you would use it in such a grind is that it is actually a cheap steel and easy to grind but you are likely not going to promote that.
Yeah, I meant "see" in the general sense meaning that it is an obvious fact such as you can "see" one knife is heavier than another by just picking them up. It is much harder to sell the idea for example that production was upgraded to minimize time after the quench before cold treatment and thus minimize stabilization of austenite. That isn't something a user can directly appreciate when looking at the knife and a lot of sales are made on direct and quick impressions.Though, you really can't 'see' a different steel outside of the name etched on the blade.
A lot depends on the market though, if you are selling to a much smaller and niche market you can use the fact that those individuals often want to be "in the know" and will soak up that kind of promotion. This is the classic "emperor wears no clothes" approach. Only an elite knife user will appreciate the work we put into our steel. This of course has people running to say "I see the difference." because if you don't see the difference you are simply not elite.
I would assume this has been done by the manufacturers, but they also have to factor in what sells, not simply what gives optimal performance. As an extreme example of this consider the smiths who work with pretty much the cheapest steels (1095 and similar) in $1000 knives. The materials cost is basically nothing, many of them even use recycled steels, but they put a huge amount of time and effort into working the steel.I wonder what the difference in labor and materials cost would be between more involved heat treats and using more expensive steels, on case by case basis.
Note inherently that the higher alloy steels are so designed to actually allow less complication in heat treatment, use of air over oil/water, less warping, inherent high stability, etc. . In many cases in industry tool uses is so focused that you don't need to care about the other properties, this is why as noted D2 is heat treated to a very coarse grain structure because it isn't used when a very one is needed. It just offers high compressional strength and wear resistance.
The first question you should always ask is simply what are you trying to achive? Then this is followed with, how does what you do obtain those goals and what are the compromises made. The answers to these questions are very telling especially the last one. Now turn around and ask those exact same questions to a competiting manufacturer and compare the results. Given a set of criteria, only one design/material can actually be optimal. The trick is actually figuring out the criteria.
