This recent research will be of interest to everyone who sharpens stuff.

It would appear that "C. Cem Tasan, the Thomas B. King Associate Professor of Metallurgy at MIT", knows a lot less about cutting tools than even stoneworkers from a few thousand years ago.

But I do realize that many positions in the academia profession require publishing, so I'll try to cut him a little slack for making a lame effort to do what he needs to do.

The little hair slicer they made to fit inside the SEM seems cool to me.  I'd like to see that kind of work done with other materials and tool types.

Be nice. A lot of "scientists" wonder stupidly on the most trivial questions. Takes a couple of 100k's in grants to come up with this :

"""“The basic idea is to reduce this heterogeneity, while we keep the high hardness,” Roscioli says. “We’ve learned how to make better blades, and now we want to do it.”"""

The imbeciles at SANDVIK producing those super specials steels used in paper cutting or veneer manufacturing would not've figured that out in 100 years.

P.S. Roscioli ( sic!) did not learn how to make better blades. He learned how a better blade should behave. But that sort of minor confusion is pretty much irrelevant in "science". Now might be the time for you to remember that wondrous experiment where unknown violins( claimed to be Strads )  were pitted against best new violins one could find and... seemed to be winning. In the end they didn't but at least the "scientist" told us here on MN  why : not enough time to carry the test to completion.
