Made entirely out of corrosion-resistant materials and a high-grade coating. The hooks are high carbide steel with flex technology and a Tri-Cut (groove). The grooves decrease resistance for optimal penetration, and the slightly beaked hook point helps to maintain a good hook set! This stinger features a slideable spike and extension link so the stinger fits more lures!
