How to Use a Knife Sharpener

Published in Knife Maintenance 4 mins read

Keeping your knife blades sharp is essential for safe and effective cutting. A sharpener, specifically a knife sharpener as indicated by the provided reference, is a tool designed to restore and refine the edge of your blades. Understanding how to use one correctly ensures your knives are always ready for use.

Using a knife sharpener typically involves two main phases: sharpening the blade to create an edge and then honing the edge to refine it.

Steps for Using a Knife Sharpener

While types of sharpeners vary (e.g., manual pull-through, electric, whetstone), the core principle involves material removal or alignment to restore the edge. For a common manual or electric pull-through sharpener, the process often follows these steps:

1. Sharpening the Blade

This is the primary stage where the dull edge is ground down to create a new, sharp bevel. Many sharpeners have different slots or grits for this purpose, often starting with a coarser grit if the knife is very dull.

  • Insert the base of the blade into the sharpening slot designed for sharpening (often labeled coarse or medium).
  • Draw the blade evenly through the slot, from heel to tip.
  • Repeat this process. It's crucial to use an equal number of times to sharpen both sides of the blade. Evenly. Consistency in pressure and angle (if applicable to your sharpener type) is key here. The number of passes needed depends on how dull the knife is.

2. Honing the Edge

After sharpening, the blade edge might have tiny burrs. Honing doesn't remove much material; instead, it realigns these microscopic misalignments, making the edge straighter and smoother, resulting in a keener cut. This is typically done on a finer grit setting.

  • Once sharpening is complete, then run the blade through the fine setting once or twice to hone The Edge. This fine setting is designed to refine the edge created in the previous step.
  • Draw the blade through the fine slot one or two times, applying less pressure than the sharpening step.

Tips for Effective Sharpening

  • Read the Instructions: Always consult the manufacturer's guide for your specific sharpener model, as steps and recommended passes may vary.
  • Clean Your Knife: Ensure the blade is clean and dry before sharpening.
  • Maintain Consistency: Use consistent pressure and speed when drawing the blade through the slots.
  • Safety First: Keep fingers away from the edge and stabilize the sharpener on a secure surface.
  • Check Sharpness: Test the blade on a piece of paper or a tomato (carefully!) to check if it's sharp enough.

By following these steps, particularly ensuring an equal number of times to sharpen both sides of the blade, evenly, and then using the fine setting once or twice to hone The Edge, you can effectively use a knife sharpener to keep your knives performing at their best.
