Crayola :
Vanadium will act to refine the grain of the steel matrix and during the secondary hardening Vanadium will actually breakup the primary carbides and forum V4C3 a much smaller and *MUCH* harder carbide. The reason that the CPM products can't match 52100 in terms of grain size is mainly *MASSIVE* alloy content. To clearify, they are still very fine, just a few microns, 2-4 for CPM-10V (D2 is 30+ for example).
thombrogan :
That would prevent any edge tear outs, and is probably a good idea in general because of the massive increase it will make in durability. However even though I have seen edges breakup with coarse grained steels at acute angles, it is near impossible to note any drawback to sharpness because of the insane level of cutting ability with such a profile. Wood cutters can comment on it however, they can have very high standards for sharpness.
