The first of my "ONYX" Series...Carbon-faced, Cypress-cored (2), 5-ply, 0.20" / 5mm thick.  Hard surface can cause the ball to leave fairly quickly...the blade has enough flex to hold onto the ball for superb spin-ing.  Excellent compatibility with 'tuned' rubbers. and the handle looks "sinister".   "BE DANGEROUS TO YOUR OPPONENT" !!!
