This model features an integrated karabiner end-loop. It is suitable for anglers who prefer quick access and tool attachment during fishing. The karabiner allows the knife to be clipped to backpacks, belts, or tackle bags.

6 Inch Folding Fillet Knife Product Advantages

Compact Folding Design for Easy Storage

The folding design allows the knife to be safely stored when not in use, making it ideal for travel and outdoor adventures. It reduces the knife’s size by half, allowing easy storage in tackle boxes, backpacks, or fishing gear bags.

Stainless Steel Blade for Durability and Precision

The 6-inch stainless steel blade offers excellent corrosion resistance, ensuring that the knife will withstand saltwater environments. The blade is thin and flexible, making it perfect for detailed filleting and bone removal.

Ergonomic TPR Grip for Comfortable Use

The TPR grip provides a secure, non-slip hold, making it easy to operate the knife with one hand. The comfortable design reduces hand fatigue, allowing you to fillet multiple fish comfortably and efficiently.

Corrosion and Rust Resistance

The blade is coated with a corrosion-resistant layer, making it ideal for saltwater fishing. This feature ensures that the knife maintains its sharpness and reliability over time, even in harsh environments.

6 Inch Folding Fish Knife Manufacturing Process

1. Material Sourcing:
   We source 420 stainless steel for the blade and certified hardwood or TPR for the handle. All materials are traced to approved suppliers to ensure stable production quality.
2. Blanking and Profiling: 
   The blade blanks are cut or stamped into the 6-inch profile. This step shapes the thin flex zones needed for accurate filleting.
3. Heat Treatment: 
   Each blade is hardened and tempered to reach the required hardness and toughness. Controlled heat treatment maintains proper flexibility and edge durability.
4. Grinding and Edge Thinning: 
   The bevels are ground, and the edge is thinned to achieve the ultra-thin fillet blade geometry. This ensures the correct blade thickness before final sharpening.
5. Finishing and Corrosion Protection: 
   The blade surface is polished and coated as needed. Sample batches undergo salt-spray checks to confirm corrosion resistance.
6. Handle Shaping and Assembly: 
   The handle material is shaped, fitted, and assembled onto the blade with bonding and rivets. The parts are aligned to ensure a stable structure.
7. Sharpening and Edge Setting: 
   The knife is sharpened to the specified angle, and the cutting edge is adjusted according to RTI’s test protocol.
8. Quality Inspection: 
   Each unit is inspected for surface finish, assembly, sharpness, blade flexibility, and corrosion performance.
9. Packaging and Labeling: 
   Finished knives are packed in standard boxes or OEM packaging. Labels, barcodes, and private-label details are applied based on customer requirements.
10. Shipment Preparation: 
    Orders are packed for export according to shipping terms, and documentation is prepared for delivery and customs requirements.
