That self sharpens is a MYTH. DU do shed its edge barbs as its tensile strength is low. SO It drops any edges of the mushrum edge that naturally form during terminal ballistic interactions. That is NOT self sharpening, The tip is not kept SHARP by any magical interaction. All it does is lose edge material that could form a secodn edge that would increase penetration resistance.

@Biketunerfy maybe you should read less scientific american and read more proper papers. The sheddign of the blunt edges is nearly irrelevant toward penetration. Because the so called"burning" expends energy, energy that comes from the projectile... and less available energy to break the armor therefore ( modern armor is Energy expenditure oriented, not resistance oriented) in an attempt to explain to layman the term SHARPENING is used, but sharpness is IRRELEVANT when you have a projectile trying to progress trough a cristaline solid at a speed higher than the speed of sound on given material.
