I remember my Grandpa, who taught me Steelheading, talking about the "Cherry Bobber". I think he caught a 20#er on it. I was very young and never used one, but Lifter is correct. It had a col type blade above an oblong ball. Never heard or seen a "Apple Knocker"? Never posted pics here either. Way above my pay grade.
