The Xiom Ice Cream AZX has a koto outer ply, a limba inner ply, and a kiri core. However, sandwiched between the koto and limba plies, the AZX has an outer carbon ply of ZLC on one side and an outer ply of ALC on the other side. This allows its user to have different playing characteristics on each side. The ALC allows for a softer, stiffer, and springier feel while the ZLC allows for a harder and more elastic feel. These outer carbon plies are felt immediately on most strokes. A truly special blade that allows you to tailor it to your style of play. Weight:88g
