JBL Rotating Long Winged Rockpoint Speargun Tip

We like to think it'd be easier to dull a diamond razor blade than it would be to dull this rotating rockpoint spear tip against reef rocks. The short tapered, machine cut spear point holds off against rock hits well, yet still pierces through the toughest, most tenacious fish of the reef. This spearpoint has a double barbed wingspan of 4 inches, and 6mm threading.
