- Ring Eye Shank: Tube eye with smooth ring finish prevents line damage or cutting.
- Sharp Hook Point: High-carbon steel undergo 3 grinding processes for long-lasting sharpness without dulling.
- Forged Hook Body: Secondary flattening process boosts longitudinal tensile strength without thickening the wire, maintaining flex and toughness.
- Wide Bend & Offset Point: Rounded gap distributes stress evenly to resist bending; wider gap and offset point design make it harder for fish to unhook after swallowing.
