That's fascinating (and even better, from the point of view of narrowing down the knife - if such a profile is gotten from the forensic radiology).Also, Ka-bar knives are made from 1095 Chrome/Vanadium plain tool steel with a Rockwell Hardness of 56-58 HRC. Apparently the tip is prone to breaking off and it has that black epoxy powder-coating which can wear off.
As a basis of comparison, Buck knives are made from 420HC stainless steel which also has a Rockwell Hardness of 56-58 HRC.
MOO
The chromium and vanadium (particularly the vanadium) are very rare. I assume Ka-Bar's "recipe" is slightly different than all other similar recipes. If it was relatively new, then that black epoxy coating is extremely interesting and makes me hopeful.
I would think, at a minimum, that forensic radiology would narrow down the knife type to just a couple of manufacturers, but I wouldn't be surprised if it could narrow it down to a particular brand, even to a factory.
From the FBI's POV, this is an excellent opportunity to bring together specialists in several fields, across a few states.
IMO.
