The RAZR Black irons have the black PVD finish found in other Black X Series clubs in Callaway's 2012 lineup, a look that some might find cool but whose practical purpose is in reducing glare.
Both sets have an integrated clubface/undercut cavity and the usual Callaway medallion on the back to dampen vibration and improve impact sound. The X HL irons have wider soles.
The irons hit retail on March 16, 2012. The RAZR Black set is priced at $799 with steel shafts/$999 with graphite; the HL X set $599 with steel and $799 with graphite.
Both sets offer the option of subbing two RAZR X HL hybrids (pictured on previous page) for two of the irons. Doing so doesn't change the price of the graphite sets, but adds $100 to the price with steel shafts.
