Wholesale 3.5 Inch Stainless Steel Clam Knife with ABS Handle

A 3.5″ clam knife is designed for opening clams and other shellfish that require controlled prying force rather than cutting. Unlike kitchen or fillet knives, it features a short and thick blade that resists bending when inserted into hard shells.

This type of knife is widely used in seafood markets, restaurant kitchens, and shellfish processing, where tools must withstand repeated pressure without losing stability.

The RTI 3.5″ clam knife uses a rigid stainless steel blade with a reinforced tip to improve insertion strength, combined with a non-slip ABS handle and large finger guard to maintain grip control and reduce hand injury during continuous use.

Why a Blunt Tip is Used Instead of a Sharp Point

Unlike standard knives, a clam knife is not designed for cutting. The tip is intentionally modified to improve safety and usability.

• A sharp tip can easily slip on hard shells.
• A blunt or semi-rounded tip provides better contact stability.
• It reduces the chance of puncturing hands during shucking.

This design allows the knife to enter the shell gap while maintaining control, especially for users handling large volumes of shellfish.

Quality Control of 3.5″ Clam Knife

To ensure consistent performance in shellfish shucking applications, each batch of clam knives is controlled through the following key checkpoints.

• Blade material: Food-grade stainless steel (3Cr13 / 420J2), verified by incoming material inspection.
• Hardness: HRC 52–55 after heat treatment.
• Blade thickness tolerance: ±0.1 mm.
• Surface finish: No burrs, polished edge inspection 100% visual check.
• Handle material: Injection-molded ABS, dimensional consistency control per batch.
• Blade-to-handle bonding strength: ≥150N pull test standard.
• Corrosion resistance: 24-hour salt spray spot test sampling (ASTM B117 reference).
• Functional test: Random sample clam-shucking simulation per batch.
