Sounds completely nutty. I like it!
This is probably not so hot for profit, but would be a great service to the community - both users and manufacturers.
Some thoughts -
1. Each steel should be heat treated as "optimal" for that particular steel type. Of course, optimal is up for debate. If the project goes long enough, it might be possible to make knives of the same material in different hardnesses. Regardless, I'd be interested in how the steel would perform in a manufactured hardness, which wouldn't be the same for everything.
2. Configure the handle for cord-wrap, or two simple holes that could be used for Becker-style handles. Simple handles could be mass-produced or another item for the secondary market. Make handle holes as simple as possible to reduce manufacturing costs.
Edit - Just looked at the blank. I like the general blade shape, but I think the handle has too many holes. Minimize it to 2 holes for Chicago screws. Maybe three or four if absolutely necessary for a cord wrap. What hole pattern does, say, Strider or Ek use for cord wraps? Actually Ek may be a good model - anybody know if the same hole pattern was used for their 3-screw/scales and cord wrap handles? Reducing the holes saves time and money. Besides, if it's too convenient, then people may start snapping these up for regular use

I also agree that the guard should be a bit smaller, more in line with the edge. That front finger pocket is deep enough to provide a functional guard. Don't add a seperate choil. (end edit)
3. I'd prefer "blind" blades with Cliff's A, B, C, D scheme. The codes could easily be available to people who wanted them. A compromise would be to put the steel type on the handle, where it would be covered up by the handle material.
4. Blade size and design will have a big effect on what types of tests can be done. For example, you can't really chop with a 3" blade. I'm not advocating for a huge chopper design, but a small slicing pattern is going to favor harder steels. I'd like to see a somewhat thicker blade that can be beaten a bit to test resistance to chipping, etc.
5. Offer a subscription program for these. I'd rather pay for the year, or have a credit card on file, or something that ensures I don't have to scrounge around for every single blade, and don't have to remember to submit an order.
6. I know they don't see much use in modern folders, but non-stainless steels should be included at some point - 52100, 01, etc. Hitachi blue and white would be great, but may not be practical. Maybe use a 2:1 or 3:1 ratio of normal production steels to more esoteric stuff.
