Frequently Asked Questions (FAQ)

Q1: What customization services are available for promotional knives?
A: We offer a comprehensive range of customization services to meet your branding needs, including:

  • Laser engraving for logos, text, or designs on the blade or handle

  • Custom colors for the handle (beyond standard black)

  • Custom packaging with your branding

  • Blade style selection to match your market preferences
    These services make our knives ideal for corporate gifts, promotional events, and retail branding.


Q2: What type of blade does this spring-assisted knife use?
A: This knife features a 3Cr13 stainless steel blade, which offers good corrosion resistance, durability, and edge retention. You can choose from various blade styles, including single edge, double edge, tanto, dagger, serrated, and more. This flexibility allows you to select the style that best suits your brand and target audience.


Q3: What makes this a "large-sized" OTF knife?
A: This knife is classified as "large" with a total length of 24.1 cm (9.49 inches) and a blade length of 10 cm (3.94 inches) . It weighs 283 grams, offering a substantial feel. This size makes it suitable for tactical, outdoor, and promotional applications where a more robust tool is preferred.


Q4: What materials are used in the construction?
A: The blade is made from 3Cr13 stainless steel with a thickness of 3 mm. The handle is constructed from zinc alloy and features a rubberized grip for secure, comfortable handling. The handle is available in standard black, with custom colors available upon request.


Q5: What additional features does this knife have?
A: In addition to the spring-assisted OTF mechanism, this knife includes:

  • An integrated glass breaker for emergency situations

  • A pocket clip for convenient everyday carry

  • A rubberized handle for a secure grip

  • A hard black box + nylon bag for premium packaging


Q6: Is this knife suitable for brand promotions and corporate gifts?
A: Absolutely. Its customizable nature, premium features (glass breaker, rubberized grip), and robust packaging make it an excellent choice for high-value corporate gifts, promotional items for trade shows, or branded merchandise for retail. The laser engraving service ensures your logo is displayed prominently.


Q7: What color options are available for the handle?
A: The standard color is black. However, other colors or patterns can be customized for bulk orders. This allows you to match the knife to your brand colors or specific promotional themes.


Q8: What packaging is included with bulk orders?
A: Each knife comes in a hard black box with a nylon bag for protection and a premium unboxing experience. Custom packaging options with your branding are also available for bulk orders.


Q9: Is the knife safe to carry and use?
A: Yes. The retractable OTF design allows the blade to be fully retracted into the handle when not in use, preventing accidental cuts. The spring-assisted mechanism requires deliberate action to deploy. Always follow safe handling practices and be aware of local regulations regarding automatic knives.


Q10: Can I get a sample before placing a bulk order?

A: Yes. We support sample orders so you can evaluate the product's quality, feel, and customization options before committing to a larger quantity. Contact our sales team to arrange a sample.
