Stainless Steel Fishing Fillet Knife Quality Control

To ensure stable quality and consistent performance, this 6 inch fishing fillet knife is produced under controlled manufacturing processes, with key checks applied from raw material to finished product.

Material Control

• Stainless steel is selected from commonly used grades such as 3Cr13 / 420J2 or equivalent, ensuring good corrosion resistance and durability.
• Key material properties are verified to maintain consistent performance in different environments.
• Handle materials (PP+TPR) are tested for basic strength, flexibility, and anti-slip performance.
• Incoming materials are checked for surface condition and dimensional consistency.

Blade Processing

• Blades are ground using controlled processes to maintain a stable edge angle for consistent sharpness.
• Heat treatment is applied to achieve a hardness range of HRC 52–56, balancing edge retention and toughness.
• Blade thickness and straightness are controlled within standard production tolerances.
• Optional coating is applied to improve surface smoothness and reduce sticking during use.

Assembly Process

• Blade and handle are assembled using mechanical fixing combined with thermal bonding.
• Each unit is checked for handle stability and alignment.
• Functional parts such as the finger guard and sheath are verified during assembly.

Inspection & Testing

• 100% visual inspection before packaging to check blade finish, edge condition, and handle quality.
• Sample-based cutting tests are conducted to ensure consistent performance.
• Salt spray testing (24–48 hours) is used to evaluate corrosion resistance.
• Final products are checked for overall structure, balance, and usability.
