Sharpening a knife blank is an essential skill that every knife enthusiast should master. A sharp knife not only makes meal preparation easier and safer but also prolongs the life of your knives. Whether you have just purchased a new knife blank or noticed that your old one has lost its sharpness, this guide will teach you how to sharpen a knife blank like a pro.
Before we dive into the sharpening process, it’s important to understand what a knife blank is. A knife blank is the blade of the knife without a handle. It doesn’t have an edge bevel or a sharp cutting edge. Sharpening a knife blank involves creating a bevel, refining the edge, and polishing it to achieve the desired sharpness.
To sharpen a knife blank, you will need a set of sharpening stones with different grits. Start with a coarse grit stone to shape the edge, then progress to finer grit stones to refine and polish the blade. A honing rod or a leather strop can also be used to maintain the knife’s sharpness after sharpening.
Step 1: Establish the bevel
To establish the bevel, set your knife blank against the coarse grit sharpening stone at a 20-degree angle. Move the knife back and forth across the stone, applying light pressure. Repeat this process until the edge forms a flat bevel along the entire length of the blade. Remember to maintain a consistent angle and apply even pressure to ensure an even bevel.
Step 2: Refine the edge
Once the bevel is established, switch to a finer grit stone to refine the edge. Follow the same back and forth motion, applying light pressure. This step removes any scratches left by the coarse stone and further sharpens the blade.
Step 3: Polish the blade
After refining the edge, it’s time to polish the blade for a razor-sharp finish. Use a honing rod or a leather strop to gently swipe the blade in a slicing motion. This process aligns the edge, removes any remaining burrs, and gives you a mirror-like finish. Remember to maintain a consistent angle and use smooth strokes.
By following these steps, you can sharpen a knife blank to achieve a razor-sharp edge. Remember to regularly maintain your knives to ensure they stay sharp and perform at their best. Happy sharpening!
