High Quality Content by WIKIPEDIA articles! A Spinnerbait refers to any one of a family of fishing lures that get their name from one or more metal blades shaped so as to spin like a propeller when the lure is in motion, creating varying degrees of flash and vibration that mimics small fish or other prey. The two most popular types of spinnerbaits are the `in-line spinner` and `safety pin` spinnerbaits, though others such as the `tail-spinner` also exist. Spinnerbaits are used principally for catching Predatory fish such as perch, pike and bass.
