FAQ

Q1: What is the advantage of SK4 steel over standard SK5 steel blades?

A: SK4 high-carbon steel contains higher carbon content than SK5, which allows it to achieve higher hardness after heat treatment. This results in a significantly sharper cutting edge and superior wear resistance.

Q2: How does the triple-blade auto-loading mechanism work?

A: The handle features an internal magazine holding 3 blades. When the current blade is worn out, safely dispose of it, slide the push-button all the way back, and slide it forward again. The next blade automatically loads into place.

Q3: Can we order custom colors and have our logo printed on the knife?

A: Yes. We provide full OEM/ODM services. We can custom-inject the handle in your brand colors, print/laser-etch your logo on the metal sheath or plastic housing, and design custom retail blister cards.

Q4: What is the MOQ and delivery time for OEM wholesale orders?

A: The standard MOQ for custom branding and colors is 2,000 pcs per model. The average lead time is 20–30 days depending on the customization requirements.
