Collection: Blades

If your scraper or utility knife's blade is rusty, chipped, cracked, or bent, it's time to replace it. If the blade struggles to cut through objects, it's dull and not as sharp as it used to be. Jagged or uneven cuts indicate worn blade edges, potentially damaging surfaces. If the blade doesn't leave a clean swipe or scrape, or vibrates or makes noise, it's time to replace it. Regular blade replacement is crucial for tough jobs like cleaning after construction or scraping cement and mortar, as they wear out quickly.

To change blades on scrapers and utility knives, ensure the tool is locked to prevent the blade edge from being exposed. Press the blade-change or safety-release button to unlock the blade. Remove the old blade, align the new blade with the slot or notch, and slide it in until it locks into position. For scrapers, push the slider forward to fully expose the blade. Lock the new blade in place by pulling the slider back. Hold blades by their dull sides to prevent injuries and dispose of used blades in a designated sharps container.

Carbon steel, stainless steel, and carbide blades are primarily made of different materials and have varying properties. Carbon steel blades are sharp and easy to sharpen, making them ideal for clean cuts. However, they are susceptible to rust, so regular cleaning and oiling are necessary. Stainless steel, with at least 10.5% chromium content, resists rust and corrosion well, making it suitable for wet or humid environments. Carbide blades, made with hard carbide tips, are the strongest and least likely to break, making them ideal for heavy-duty work. Although they are more expensive and require special tools for sharpening, their long-lasting performance often compensates for the higher initial cost.

Special blades are designed for various cleaning and scraping jobs, ensuring surfaces are safe and clean. Razor blade scrapers are suitable for small tasks like removing soap scum, dried paint, baked-on food, and old caulk. Urinethane blades are used in factories for cleaning conveyor belts and are durable and long-lasting. Plastic scraper blades are safer for plastics, wood, and composite materials than metal blades, making them useful in window tinting and automotive industries. Heavy-duty carbon or stainless steel blades are ideal for tough jobs like removing paint, gum, or glue from tile floors. Compact scrapers with stainless steel blades are ideal for small spaces and tough industrial materials. These blades ensure the right tool is used for any job, making it safer, longer-lasting, and cleaner.
