The Patch Puller Worm is made of solid brass with strong steel fingers. The Ball and Bullet Puller is a brass bore guide that centers the pointed screw on the stuck bullet for easy removal and works well for removing stuck shotgun wads, sabots, and patches. The Super Jag was machined from solid brass with a long stepped shank to prevent patches from binding. The Bronze Bore Brush is designed for scrubbing out lead and plastic deposits. And finally, the Cotton Bore Swab is included for lubing the bore.
