The core design features of the fine axis raft fishing hook revolve around lightweight, high sensitivity, and strong fish catching ability. Through structural optimization such as fine hook strips, wide hook doors, and inward hook tips, the hook achieves a balance between bait inlet, fish message transmission clarity, and catch rate during deepwater fishing. The specific analysis is as follows:
1. Fine axis design: pursuit of lightweight and sensitivity
Thin hook bar: The diameter of the hook bar of a thin shaft raft fishing hook is usually more than 30% thinner than traditional fishing hooks (such as the flat hitting Jinhaixi No. 4 hook bar which is only 0.35mm), and it is lighter in weight. This design reduces the resistance of fish when sucking bait, allowing the bait to naturally sink, especially suitable for slow drifting of bait in deep water fishing, reducing fish alertness.
Sensitivity improvement: The slim axis design makes fish signal transmission clearer. When the fish lightly touches the bait, the hook body can respond quickly, and the angler can perceive the fish mouth through small movements of the rod tip, improving the success rate of catching the mouth. For example, when fishing for yellow tailed sturgeon on a raft, using the No. 5 spineless slender hook can catch up to 18 fish per hour and increase the hit rate by 25%.
2. Hook door width and inward hook tip: dual protection of strong stinger and anti unhooking
Optimization of Hook Door Width: The hook door width of the thin axis raft fishing hook is more than 20% wider than that of the same size sleeve hook (such as the 5.0mm Jinhaixi Hook Door vs 4.2mm sleeve hook of No. 3). Even if the fish mouth is skewed, the hook door can still be securely attached to the corners of the mouth, reducing the phenomenon of 'empty hook during rod pulling'. For example, when fishing for about 1 pound of crucian carp, the unhooking rate of the Jinhaixi fish hook decreases from 30% of the sleeve hook to 12%.
Hook tip inward design: The hook tip adopts a 15 ° inward angle, which fits the structure of the fish lip bone. The depth of the fish hook is deeper (up to 2mm), which effectively increases the contact area between the fish hook and the fish lip and reduces the decoupling rate compared to the straight hook (1.5mm depth of fish hook). At the same time, the inward hook tip can reduce the risk of bottom hanging, making it suitable for fishing in complex waters.
3. Material and craftsmanship: balance between lightweight and strength
High carbon steel or flat punching process: Thin shaft raft fishing hooks are often forged with high carbon steel (such as Wolf Clan thin shaft crank hook 6203CP) or flat punching process (such as Jinhaixi), which improves strength while ensuring lightweight. For example, the Pingda Jinhaixi No. 4 hook can withstand a tensile force of 3.5kg, achieving the characteristics of "light as nothing, strong as tough steel".
Coating treatment: Some models use PTFE coating to enhance corrosion resistance and are suitable for long-term deep water use. For example, the super smooth Jinhaixi can maintain a smooth hook body and reduce sediment adhesion in seawater environments.
4. Hook type adaptability: Fine tuned design for different fish species
No backstabbing: Suitable for competitive speed fishing or scenes that require quick unloading of fish (such as No.6 Thornless Golden Sea Evening), the unloading time is reduced by 50%, improving fishing efficiency.
There is a backstab design: suitable for wild fishing or catching large fish (such as the No.3 Thorn Golden Sea Evening), with a backstab design to prevent fish from shaking their heads and detaching, especially suitable for powerful fish such as carp and grass carp. For example, on the 8th, the success rate of fishing for carp with corn kernels hanging from the Golden Sea is 18% higher than that of Iseni.
Long handle design: It is convenient to hang live bait (such as live shrimp and loach), and the long handle keeps the bait at a distance from the sub line to avoid entanglement. For example, on the 2nd, there is a barbed Jinhaixi hook that runs through the back of live shrimp, with a long stem (9mm) to prevent the shrimp from entangling the string, and the hook tip is inward to prevent the shrimp from falling off, resulting in a fish catching rate of up to 80%.
