There are no compromises with this blade. Certran Carbon, an artificial fibre, has been combined with a new carbon layer and has been placed directly under the Koto outer veneers. The result is extreme hardness for the latest model in the Balsa Carbo Line. Combined with the 4 mm thick balsa core, this makes for an astonishingly light blade. At 75g the BALSA CARBO CERTRAN FIBRE is one of our lightest blades ever. It is also superfast. Even faster and harder than the CARBO FLEECE. BALSA CARBO CERTRAN FIEBRE is an attacking blade for all players who stay close to the table and play a ferocious power game.
