Why is stainless steel so hard to sharpen?

Stainless steel is a type of steel that contains at least 10.5% chromium, which makes it more resistant to corrosion and staining than other types of steel. However, this added corrosion resistance also makes stainless steel more difficult to sharpen compared to other types of steel.

One reason why stainless steel is harder to sharpen is because it is a softer and more ductile material than other types of steel. This means that it is easier to bend and deform than harder steels, which can make it more difficult to create a sharp edge. Additionally, the presence of chromium in stainless steel can make it more difficult to remove material from the blade during the sharpening process, as the chromium can cause the blade to become more brittle and prone to chipping.

Another reason why stainless steel is harder to sharpen is because it is more prone to developing a burr, which is a thin layer of material that forms on the edge of the blade during the sharpening process. A burr can cause the blade to feel sharp to the touch, but in reality, it is not a true sharp edge and can dull quickly. Removing the burr requires a finer grit sharpening stone or honing rod, which can be time-consuming and requires more skill.

Overall, stainless steel is harder to sharpen than other types of steel due to its softer and more ductile nature, as well as its tendency to develop a burr during the sharpening process. However, with proper technique and the right tools, it is possible to sharpen a stainless steel knife and maintain a sharp edge.

Is it better to sharpen a knife wet or dry?
