Quick Answer
Most common mistakes when sharpening knives include improper angle and pressure, failing to maintain a consistent sharpening path, and not checking the edge frequently enough, often resulting in a dull or uneven edge.
Insufficient Angles and Pressures
When sharpening knives, maintaining a consistent angle is crucial. A common mistake is applying too much pressure, causing the blade to flex and deviate from the desired angle. Aim for a pressure of around 10-15 pounds, and use a sharpening guide or jig to ensure the correct angle. For a standard edge, use an angle of 20 degrees for a straight edge or 30 degrees for a serrated edge. If using a sharpening stone, start with a coarse grit, around 400-600, and progress to finer grits, 1000-1200, for a smooth finish.
Incorrect Sharpening Path
Another common mistake is not maintaining a consistent sharpening path. Move the knife in a smooth, even motion, maintaining contact with the sharpening stone or steel. Apply gentle pressure and move the knife in small, gentle strokes, typically 6-8 inches long, and repeat for several passes. This helps to maintain a consistent edge and prevents the development of a “wavy” or uneven edge.
Inadequate Edge Inspection
Sharpening a knife is not a one-step process. Regularly inspect the edge for sharpness and evenness. Use a sharpness testing tool or perform a simple scratch test on a piece of paper to check for sharpness. This helps to identify areas needing further sharpening and prevents over-sharpening, which can lead to a weakened edge. Check the edge every 2-3 strokes or after a change in sharpening direction.
