Fuji Guides combines Alconite rings and S-4 Stainless Steel Frames to create their Concept Surfcasting Guides - a new generation of high-frame, small-ring guides that are among the lightest on the market today. The secret of the Fuji BLCAG guide lies in its use of Alconite - a highly compressible, super-lightweight ceramic that offers above average strength and long-term durability.
