John Fabanich was issued a patents for advanced asymmetric cores in 1990 and 1992 (U.S. patents 4913429 and 5125656). This type of core was used in the JPF Axe. Years earlier, Mr. Fabanich marketed the first two-piece polyester ball (the Fab) and later, the first widely popular two-piece urethane ball: The Faball Hammer.
I believe the Phantom is the first asymmetric that has the distinction of being manufactured and marketed to deliberately take advantage of core asymmetry through advanced drilling techniques.
