Penetrator composite blades are manufactured from glass fiber and epoxy resin using the same advanced vacuum molding process and high temperature digitally controlled and monitored cure cycle as the Carbon Fiber range. The blades are CNC cut to ensure accurate profiles. There is progressive flex along the blade for efficiency and high durability, as these are the ideal fin for shore based and boat based freediving and spearfishing.

3 year warranty against blade breakage provided by Penetrator.
