Fish saw blade

Professional fish saw blades must be made from high-carbon steel or stainless steel (SUS304/420) to ensure corrosion resistance against saltwater and fish acids. The teeth should undergo high-frequency induction hardening to reach a hardness of HRC 60-65, ensuring the blade remains sharp while the body maintains the flexibility needed to prevent snapping under high-speed tension.

The choice of TPI (Teeth Per Inch) depends on the state of the fish. For frozen fish, a 3 TPI or 4 TPI blade is recommended to allow for efficient chip removal and fast cutting. For fresh or chilled fish, a finer 6 TPI blade provides a smoother cutting surface and reduces meat wastage. Always ensure the tooth set is balanced to prevent the blade from binding in the bone.

Since the blade directly contacts food, it is critical to verify compliance with FDA (Food and Drug Administration) or EC 1935/2004 standards for food contact materials. You should request material analysis reports and NSF certification if available. Additionally, ensure the manufacturing process follows ISO 9001 quality management systems to guarantee consistent blade thickness and welding strength.

Buyers must confirm the exact length (mm), width, and thickness (commonly 0.5mm to 0.6mm). The welding point is the most vulnerable area; ensure the supplier uses automatic laser welding or butt welding technology, which results in a seamless joint that prevents vibration and premature breakage during high-speed rotation.

The main risks include rusting during maritime transit and welding failure. To mitigate this, require suppliers to use VCI (Volatile Corrosion Inhibitor) paper or anti-rust oil coating for packaging. For quality assurance, use Made-in-China.com's Secured Trading Service to ensure payment is only released after the goods pass a third-party inspection for blade straightness and weld integrity.

Negotiate based on annual volume rather than single orders to secure a 10-20% discount. Ask for customized branding (laser etching) on the blades for orders exceeding 500 pieces. To ensure stability, prioritize suppliers on Made-in-China.com who carry the 'Audited Supplier' badge, as they have undergone rigorous on-site verification of their production capacity.

Fish saw blades are classified as sharp tools; therefore, heavy-duty protective packaging (plastic edge guards and reinforced wooden crates) is mandatory to prevent injury to handlers and damage to the teeth. Ensure the HS Code (typically 8202.20) is correctly declared to avoid customs delays or incorrect duty applications in the destination country.
