Design Concept: Offset Iseni Hook
- Combines the wide gap and sturdy wire of traditional Iseni hooks with a 15-degree offset hook point.
- Creates an optimal hook-setting angle once inhaled, making it difficult for fish to spit or escape.
- Designed to significantly reduce unhooking and fish loss.

Offset Point Iseni Fishing Hooks
- Offset point hook shank design
- Available in barbed (#1–#20) and barbless (#1–#15) options
- Made from high-carbon steel
- Pack quantity: 40 pcs / pack
Fishing Hook Comparison & Wire Gauge Explanation
- Exaggerating hook strength requires thicker steel wire, similar to oversized lines.
- While a heavy wire hook offers strength, heavy hooks hinder fish suction and weaken float signals.
- Our Iseni hooks balance wire gauge and strength within a reasonable range for optimal sensitivity.

Hook Point Durability & Corrosion Resistance Comparison
- 2. Hook point stays sharp even after piercing fish 40 times, preventing unhooking during retrieval.
- Dull hooks fail to pierce deeply, leading to lost fish.
- 3. Superior rust resistance ensures hooks do not rust after previous use.

Electroplating Quality Comparison
- Our Iseni hooks remain rust-free after soaking in natural water for 5 days due to smooth and uniform electroplating.
- Other brand hooks show uneven electroplating and rust easily after 5 days of soaking in natural water.
- Rust resistance is directly related to the electroplating process; a smooth, even coating prevents rust.

Iseni Hook (Offset Point)
- Symmetrical hook shank with smooth electroplating to protect line under stress.
- High-carbon steel construction with high 5H hardness for maximum strength.
- Multi-ground sharp hook point for quick, deep penetration.
- Smooth rounded bend evenly distributes force when fighting large fish; barbed design prevents unhooking.
- Forged back design enhances overall toughness and durability.
