Folding Pocket Knife Product Details

1. Material – Aluminum Alloy Construction

The knife body is made of aluminum alloy, providing a combination of lightweight structure and high strength. It offers reliable resistance to corrosion and rust, making it suitable for both freshwater and saltwater environments.

2. Blade – 5CR15 Stainless Steel

The blade uses 5CR15 stainless steel, which delivers stable hardness and good wear resistance. It ensures smooth and efficient cutting for fishing line, bait preparation, and light utility tasks.

3. Ergonomics – Comfortable Grip Design

The handle is designed with a smooth surface and compact shape, allowing a comfortable grip during use. It improves control and reduces hand fatigue in repetitive cutting situations.

4. Structure – Folding Safety Design

The folding structure allows the blade to be safely stored when not in use. This design improves portability and reduces the risk of accidental injury during carrying or storage.

5. Function – Keyring & Multifunction Use

Equipped with a quick-release keyring, the knife can be easily attached to keys, backpacks, or fishing gear. The integrated multifunction design also supports tasks such as package opening, fruit peeling, and light cutting work.

Related Folding Pocket Knife Options

Besides this aluminum folding pocket knife, RTI also offers additional models with different handle materials and structures to meet various market needs.

For users who prefer a softer and more comfortable grip, the TPR Handle Folding Pocket Knife (RTI-FK90) is a practical option. This model focuses on basic functionality and cost control, making it suitable for entry-level markets and bulk distribution.

For applications requiring more outdoor convenience, the Folding Pocket Knife with Carabiner (RTI-FK91) features an integrated clip at the handle end, allowing easy attachment to backpacks or gear.

Compared with these models, the current aluminum folding pocket knife provides a more rigid structure and improved durability, making it suitable for users who prioritize strength and long-term use.

Quality Control & Manufacturing Standards

RTI controls the full production process from raw material selection to final inspection, ensuring stable quality for OEM and bulk orders.

Raw Material Verification

Aluminum alloy and 5CR15 stainless steel are sourced based on defined grade standards.

• Hardness of blade material is controlled within HRC 54–56.
• Incoming materials are checked by spectrometer analysis and hardness testing.

CNC Machining & Blade Processing

• Handles are manufactured using CNC machining centers to maintain dimensional tolerance within ±0.05 mm.
• Blades undergo precision grinding and edge sharpening, ensuring consistent edge angle and cutting performance.

Surface Treatment Process

• Aluminum parts are treated with anodizing (10–15 μm thickness) to improve corrosion resistance and surface durability.
• Coating adhesion is tested through cross-cut testing (ISO 2409 standard).

Assembly & Functional Inspection

Each unit is assembled under controlled procedures. Key checks include:

• Folding mechanism smoothness (open/close cycle test).
• Spring gate elasticity and response.
• Blade alignment and handle fitting tolerance.

Durability & Corrosion Testing

• Salt spray test (24–48 hours) to evaluate corrosion resistance.
• Drop test (1–1.2 m) to simulate accidental impact during use.
• Repeated folding test to ensure structural reliability.
