Product Introduction
Redefining personal care with circular economy principles
The Single Edge Industrial Utility Blades are the heavy-duty workhorses of the professional maintenance, automotive, and glass industries. While double-edge blades focus on grooming, the single-edge blade is designed for High-Pressure Scraping and Precision Slitting. Featuring a reinforced steel spine (back), these blades provide the rigidity required to remove industrial adhesives, paint overspray, and decals from flat surfaces without the blade flexing or breaking. For 30 years, our manufacturing facility in Ningbo has been a world leader in single-edge blade production, mastering the specialized process of "back-wrapping"—where a folded metal sleeve is permanently crimped onto the non-sharp edge. This spine not only adds structural strength but also makes the blade safe to handle and compatible with a wide range of industrial scrapers and specialized cutting tools. We use high-carbon SK5 steel, ground to a robust 60-degree angle to ensure the edge is tough enough to resist dulling when used against hard glass or metal surfaces.
Technically, our single-edge blades are engineered for Durability and Safety. Each blade undergoes a specialized tempering process that prevents the steel from becoming brittle, allowing it to withstand significant lateral force. The edge is precision-honed and then coated with a dry-film lubricant to reduce friction during scraping tasks. A key innovation in our production line is the Micro-Crimp Spine. We utilize high-pressure hydraulic presses to ensure the aluminum or steel back is perfectly aligned with the blade, preventing any "blade-slip" during heavy-duty use. For the automotive and painting industries, we offer "Non-Scratch" versions where the blade edge is ground to a specific micro-radius to remove material while protecting the underlying substrate. Our factory is fully ISO 9001 certified, and we employ automated optical inspection to ensure that the spine is centered and the edge is free from burrs or irregularities, which is critical for smooth scraping performance.
For industrial supply distributors, hardware wholesalers, and automotive repair chains, our Single Edge Industrial Blades represent an essential high-volume SKU. We understand the logistics of high-use consumables; therefore, we provide these blades in a variety of industrial packaging formats, including Bulk 100-Blade Safety Sliders and individually wrapped units for retail. Our massive production capacity allows us to offer unbeatable factory-direct pricing while maintaining the quality standards of premium global brands. We also offer full OEM customization, including custom-colored spines for brand differentiation and private-label packaging. Whether you are supplying professional window cleaners or industrial gasket manufacturers, our blades provide the rugged, reliable performance that industrial environments demand. Choosing our single-edge series is a choice for 30 years of manufacturing reliability. We provide the structural strength, the precision edge, and the high-volume supply chain to keep your customers' industrial projects on track.

Technical Details & Safety
Manufacturing Process
Blades are stamped and ground, then fed into an Automated Back-Capping Line where the spine is crimped with over 5 tons of pressure.
- Adhesion Testing: Spine is tested to ensure it cannot be pulled off the blade.
- Edge Sharpness: Verified via optical profile projectors.
- Tempering: Heat-treated to ensure the perfect balance of hardness and flex.
Safety & Maintenance
- Always use a scraper tool for large tasks; do not use the blade by hand.
- When scraping glass, keep the blade wet to prevent scratching.
- Change the blade as soon as the edge begins to chip to avoid surface damage.
- Store in a dry place; high-carbon steel can rust if exposed to moisture.
Frequently Asked Questions
The #9 is the standard 0.009" thickness for general use; the #12 is 0.012" thick for heavy-duty scraping.
If used at a shallow angle with a lubricant (soapy water), these blades are standard for glass cleaning.
We offer both; aluminum is standard, while steel is used for high-pressure industrial applications.
In our dispensers, the blades are stacked with the sharp edge protected by the container wall.
