A Scandi convex grind knife is a popular type of knife that has a specific blade geometry, making it very versatile and durable. However, like any other knife, it needs to be sharpened regularly to maintain its cutting performance. Sharpening a Scandi convex grind knife requires some specialized techniques and tools, but with the right knowledge and practice, you can easily achieve a razor-sharp edge.
Before you start sharpening your Scandi convex grind knife, you will need a few essential tools, including a sharpening stone, a strop, and a honing compound. The sharpening stone should have a grit suitable for your knife’s initial condition, usually ranging from medium to coarse. The strop is a leather tool used for polishing the blade, and the honing compound helps remove any burrs or fine scratches left after sharpening.
To begin sharpening your Scandi convex grind knife, start by dampening your sharpening stone with water or oil, depending on the stone’s instructions. Hold the knife at a 10 to 15-degree angle against the stone, with the bevel flat against the stone’s surface. Use long, smooth strokes, pulling the knife blade towards you, consistently maintaining the same angle.
Continue sharpening the Scandi convex grind knife until a burr forms on the other side of the blade. To remove the burr, flip the knife over and repeat the sharpening process on the other side. Once the burr is gone, switch to a finer grit stone or continue using the same one if you started with a medium grit stone. Repeat the sharpening process until you achieve the desired sharpness.
After sharpening your Scandi convex grind knife on the stone, it’s important to strop the blade to achieve a polished and razor-sharp edge. Apply the honing compound to the strop and firmly hold the knife at a 20 to 25-degree angle against the strop’s surface. Pull the blade towards you, making sure to cover the entire length of the blade. Repeat this process several times, alternating sides, until you achieve the desired sharpness.
Sharpening a Scandi convex grind knife requires practice and patience, but with the right techniques and tools, you can maintain a razor-sharp edge. Remember to regularly inspect the condition of your knife and touch up the edge as necessary to ensure optimal performance in all your cutting tasks.
Understanding the Scandi Convex Grind

The Benefits of the Scandi Convex Grind
One of the main advantages of the Scandi Convex grind is its excellent slicing ability. The convex edge allows the knife to glide through materials with minimal resistance, making it perfect for tasks such as wood carving, feathering, and slicing food.
The Scandi Convex grind also excels in durability. The absence of a secondary bevel and the thick grind on the edge make it resistant to chipping and breaking, even when dealing with tough materials.
How to Maintain the Scandi Convex Grind
Proper maintenance is essential to keep your Scandi Convex grind knife in optimal condition. Here are a few tips to help you maintain your blade:
- Regularly sharpen your knife using a sharpening stone or honing tool to maintain the convex edge.
- Avoid using power sharpeners or devices that grind away excessive metal, as they can alter the blade geometry.
- Keep the blade clean and dry to prevent rust and corrosion.
- Store your knife in a sheath or protective case to minimize the risk of accidental damage.
By following these maintenance tips, you can ensure that your Scandi Convex grind knife remains sharp and reliable for years to come.
Choosing the Right Sharpening Tools
When it comes to sharpening a scandi convex grind knife, using the right tools is essential for achieving the best results. Here are some factors to consider when choosing the right sharpening tools:
1. Whetstones: Whetstones are a popular choice for sharpening knives due to their versatility and effectiveness.
