How to Sharpen a Knife: Step-by-Step Guide

1. Cleaning and Preparation

Ensure your knife is completely clean and dry before starting. Remove any dirt, residue, or oxidation from the blade.

2. Choosing the Right Grit

If you’re using a whetstone, begin with a coarse grit (400–600) to rebuild the edge, then move to a finer grit (1000–3000) to refine and polish it.

3. Sharpening Technique

Hold the blade at about a 20-degree angle to the sharpening surface. Make long, even strokes while keeping the angle steady. Repeat on both sides of the blade to achieve a balanced edge.

4. Finishing with Lux Metal Polishing Compounds

After sharpening, apply a small amount of Lux Metal compound to a soft cloth or felt wheel. Glide the blade gently while maintaining the sharpening angle.
This step:

• enhances the sharpness,

• removes micro-scratches and residues,

• delivers a mirror-like polish and a professional finish.

Testing and Maintenance

To test sharpness, slice through a sheet of paper — if the knife cuts cleanly and easily, the edge is perfect.

For long-lasting performance:

• use wooden or plastic cutting boards to protect the edge,

• clean the knife thoroughly after each use,

• refresh the edge regularly with Lux Metal polishing compounds.
