Sharpening thinning scissors requires a specific technique to maintain the integrity of the comb and blade. Here's a guide on how to do it:
-
Use a Sharpener Wand: Employ a specialized sharpener wand designed for thinning scissors. These wands usually have a very fine abrasive surface.
-
Focus on the Comb Blade: The primary blade that needs sharpening is the one with the teeth (comb blade). The other blade is typically a standard cutting blade and may be sharpened separately using different techniques or tools.
-
Angle and Stroke:
- Carefully position the sharpener wand at the exact angle that the comb blade is beveled (this is crucial for maintaining the correct cutting geometry).
- Gently slide the wand in and out of each comb slot.
- Typically, 4 to 6 strokes per slot are sufficient to restore the sharpness. Avoid applying excessive pressure.
-
Deburring: After sharpening, small burrs (tiny, raised edges) may form. To remove these and refine the cutting edge, lightly stroke each blade 4 to 6 times with the sharpener wand, following the existing bevel.
-
Cleaning: Rinse the thinning shears thoroughly under cold water to remove any metal filings or debris generated during the sharpening process. Dry them completely.
-
Lubrication: Apply a small drop of scissor oil to the pivot point of the shears to ensure smooth operation.
Important Considerations:
- Professional Sharpening: For high-quality thinning scissors or if you're uncomfortable sharpening them yourself, it's best to have them professionally sharpened. A professional sharpener has the tools and expertise to restore the blades to their original condition without damaging them.
- Type of Sharpener: Select a sharpener wand that is specifically designed for the type of steel used in your thinning scissors. Using an incompatible sharpener can damage the blades. Ceramic sharpeners are often a good choice.
- Maintenance: Regular cleaning and oiling can help extend the life of your thinning scissors and reduce the frequency of sharpening.
Disclaimer: Sharpening scissors can be dangerous. Always take precautions and follow safety guidelines. If you are not confident in your ability to sharpen your thinning scissors, it is best to take them to a professional.
