This side is designed to remove metal quickly and efficiently, allowing you to establish a new edge or repair damaged areas. Once you’ve achieved the desired shape and edge, you can switch to the finer side (usually the lighter side) to sharpen and hone the blade.
Using a Coarse Grit First
Using a coarse grit first is essential for removing metal and establishing a new edge. This process, known as “setting the edge,” involves using the coarse side of the stone to remove small amounts of metal and create a burr, a small, raised edge that indicates the blade is starting to sharpen. By using a coarse grit first, you can save time and effort in the long run, as it allows you to quickly remove metal and achieve a sharp edge. However, it’s essential to be cautious when using a coarse grit, as it can be aggressive and potentially damage the blade if not used correctly.
Switching to a Finer Grit
Once you’ve established a new edge or repaired damaged areas, it’s time to switch to a finer grit. This is where the magic happens, and your blade starts to take shape. The finer side of the stone is designed to polish and hone the edge, removing small imperfections and creating a razor-sharp finish. By using a finer grit, you can achieve a high level of sharpness and durability, making your blade perform better and last longer.
Conclusion
