SL CARBORANDUM

A Carborundum sharpening stone, also known as a silicon carbide sharpening stone, is a popular type of sharpening tool used to sharpen and hone the edges of knives, chisels, scissors, and other cutting tools. Carborundum is the trade name for silicon carbide, a synthetic abrasive material that is harder than most natural stones and effective for sharpening metal edges.
Key features and characteristics of Carborundum sharpening stones include:
1. Material: Carborundum sharpening stones are made from silicon carbide, a crystalline compound of silicon and carbon. The combination of hardness and abrasive properties makes it suitable for sharpening cutting tools.
2. Grit: Like other sharpening stones, Carborundum stones come in different grit levels, which determine the coarseness or fineness of the stone. Lower grit numbers (e.g., 120 to 400) are coarser and used for shaping and repairing the edges, while higher grit numbers (e.g., 1000 to 8000) are finer and used for honing and refining the edge.
3. Size and Shape: Carborundum sharpening stones are available in various sizes and shapes, such as rectangular, oval, or round. The choice of size and shape depends on personal preference and the type of tools being sharpened.
4. Lubrication: Carborundum stones are typically used with water or honing oil as a lubricant. The lubricant helps to float away metal particles, keep the stone clean, and prevent overheating of the blade during sharpening.
Using a Carborundum sharpening stone is generally straightforward:
1. Prepare the Stone: Soak the stone in water or apply a layer of honing oil to the surface, depending on the manufacturer’s recommendations. The lubricant helps in the sharpening process.
2. Position the Blade: Hold the knife or cutting tool at the desired sharpening angle, typically between 15 to 30 degrees, against the surface of the stone.
3. Sharpening Strokes: Move the blade back and forth across the stone in a controlled motion. Use even pressure and maintain the sharpening angle throughout the process.
4. Alternate Sides: To maintain an even edge, switch sides of the blade after a few strokes.
5. Test the Sharpness: Check the sharpness of the blade by lightly running it across a piece of paper or testing it on a material to see if it cuts smoothly.
6. Rinse and Clean: After sharpening, rinse the stone to remove metal particles and debris. Allow it to dry before storing.
Carborundum sharpening stones are durable and affordable sharpening tools, making them a popular choice for both beginners and experienced sharpening enthusiasts. With proper care and regular maintenance, they can keep your cutting tools sharp and efficient for a long time.
