Raptor X The Raptor-X is a 3X-wire treble hook whose design is inspired by one of the best treble hooks BKK ever launched: the Raptor-Z. The hook gap-shank proportions are maintained to equip the Raptor-X with excellent holding power, yet the hook point is slightly straightened to enhance the hook-up rate, further heightened by the slimmer profile of the wire and by the Hand-Ground processing technology.
