My first attempts at making simple blades and bladelets. This process uses quite a bit of material of high quality. If you have access to the material then it's not a problem and would probably save time in the long run. But if you know how to make bifaces from just about any size and shape of stone flakes of various grades of material, this technique is not worth amount of time and material involved.
I can see that this technique may be of some benefit if it is used to create flakes that will become bifaces. The skill of making bifaces will allow you to use all the various sizes these blades to make arrowheads of matched size and weight, instead of relying on the random chance that you will remove flakes of the same sizes that need minimal or no alteration. I believe that several arrowhead types in Texas were made from small blades removed from cores in this way. The harrell, perdiz, garza, and washita types come to mind.
In Europe, there is a lot of discussion on this type of technology because it is believed to be the first technology used in the production of projectile points and knife blades. This appears to be true because this technique is intuitive and easy to teach. I see a problem, however, in thinking that these types of flakes were always blades or tools. I believe many of these flakes were waste and were not used because they are very delicate.

WHAT IS HIGH GRADE STONE?
Anything you can run a 1/2" or more flake with a pressure flaker.
HEAT TREATING:
Heat treat a few FLAKES of everything you got except HIGH GRADE Raw Stone, Obsidian, Dacite, Basalt, Hornstone, Sonora, Fort Payne, or Rhyolite. Start with flakes and spalls less than 1" thick for 200°F for 24 hours to dry it out. Then raise the temp to 275°F and hold for 4 hours. Let cool down for 12 hours. Chip and compare. If no difference, put back I at 200°F for 1/2 hour, then raise to 275 for 1/2 hour, then raise to 325 for 4 hours.
Let cool down for 12 hours. Chip and compare. If no difference, put back in at 200°F for 1/2 hour, then raise to 275 for 1/2 hour, then raise to 325 for 1/2 hour, the raise to 375 for 4 hours.
Repeat with temp going up 50°F until you reach 600°F or nice chippable stone. Whichever comes first. If no good result, or things blow up, let us know.
