The blades of the FAST 400 FS-25 are rated at a hardness of 25 soft/medium, made from 100% top-quality carbon MEGAFORCE T-700 (40% more durable than the standard T-300) with a double parabolic bend (D.C.P.) and are 20 mm longer towards the heel than traditional blades.

The blade angle is 29°, unlike common carbon blades that form a curve instead of an angle. Their dimensions (790 x 190 mm) are suitable for demanding underwater fishing.

The fixed-width water rails of the new FAST guide the water to flow along the blade, achieving effective hydrodynamics, and the underwater hunter feels as though they are moving "on rails." At the same time, the dimensions and the double parabolic bend of the blade allow for movement with absolute flexibility.

The new C4 - H.Dessault 350 foot pockets are made from thermoplastic rubber and weigh only 350 grams for sizes 41-42. They are the lightest foot pockets made from thermoplastic rubber on the market today. Their ergonomic design features a pre-shaped angle of 3 degrees to enhance comfort and efficiency.
