Ruthless Ice Jig Head was designed for ice fishing, and its swimming action triggers the hunting instincts of predators. The precise balancing of the jig head causes the jig to swim with long, irregular glides from side to side like a balance lure, provoking fish to attack. The jig heads feature extremely sharp Kumho hooks.

Ruthless Ice Jig Head is highly effective when combined with, for example, an Orka Small Fish jig for both ice fishing and jigging from a boat in the open water season.

- Ice Jig Head 5 g: 3–5 cm jigs / Fishing depth: 0.5–2 meters
