The Sher-Wood RM19 Composite Stick is constructed using high modulus carbon fiber, which makes for a great strength-to-weight ratio. The shaft of the RM19 is extremely durable as well, as it is manufactured with special 100% Aramid weave on the top layer. This will also better resist impact and abrasion problems.The RM19 blade is made of filament fiberglass and polyurethane foam with 45-degree tri-axial woven carbon fibers. This maximizes the energy transfer and blade deflection while keeping the blade very lightweight.Red Shaft Dimensions: .785 X 1.180Blue Shaft Dimensions: .745 X 1.140THE COFFEY BLADE PATTERN IS AVAILABLE IN BLUE SHAFT DIMENSIONSTHE RYAN BLADE PATTERN IS AVAILABLE IN BLUE SHAFT DIMENSIONSTHE STASTNY BLADE PATTERN IS AVAILABLE IN BLUE SHAFT DIMENSIONS
