Hayabusa Fishing has three different product series in the TBL 930 Treble Hook series: Nickel, Black Nickel, and NRB (non-reflective black) with fluorine coating. TBL 930 NRB Treble Hooks are the pinnacle of treble hook innovation, a superior treble hook to traditional and/or standard treble hooks. NRB technology proves more effective in relation to hook sharpness, durability, and elements of camouflage (the fluorine coating subtly hides the hooks presence). Bass fishermen who equip their expensive hard baits, swimbaits, spoons, and/or other fishing lures with TRB 930 NRB Treble Hookswill instantly experience the difference. Take a few minutes to improve your favorite fishing lures!
