KODEX X-STRONG SEMI-BARBLESS TREBLES X-Strong Semi-Barbless Trebles, The barbed hook is used to secure the hook bait and the barbless are left to hook the fish. This result in easy unhooking of the trebles. The treble hooks are produced from high tensile strength 110 carbon, which means they will not easily straighten out. The points are extremely sharp to give maximum penetration and the welds on the treble construction are secure. They are finished in black chrome that slightly flashes like the skin tones of a silverfish, making the hooks themselves an attractant.
