Frequently Asked Questions (FAQs)

1. Are self-sharpening trimmers good?

Yes, self-sharpening trimmers are beneficial. Unlike regular trimmers, self-sharpening trimmers have blades with a metal strip along the entire length. As the trimmer moves through the hair, the metal strip rubs against the blades and sharpens them. This feature ensures that the blades remain sharp over time, preventing dullness and the development of chips or nicks.

2. How does self-sharpening trimmer work?

Self-sharpening trimmers have a metal strip along the length of the cutter. When the trimmer cuts through hair, the metal strip rubs against the blades, sharpening them. This self-sharpening mechanism ensures that the blades stay sharp and effective, allowing for precise and efficient trimming.

3. Can beard trimmers be sharpened?

Yes, beard trimmer blades can be sharpened. To sharpen the blades, you can use 180-grit and 240-grit sandpaper. It's important to assess the current condition of the flat side of the blade before sharpening. Sharpening the blades of your beard trimmer helps maintain their cutting performance and prolongs their lifespan.

4. Do self-sharpening blades really work?

Self-sharpening blades do not sharpen themselves. They have a set of hardened steel blades attached to the sheath or knife block where they are stored. Each time the blade is inserted or removed, the edge is drawn through the sharpener, effectively sharpening it. This mechanism ensures that the blade remains sharp and ready for use.

5. Why won't my clipper blades cut after sharpening?

If your clipper blades won't cut after sharpening, the blade drive may be the issue. The blade drive holds the socket in place to drive the cutter evenly along the blade. If the blade drive is not working properly, it can affect the cutting performance of the blades. Checking and ensuring the proper functioning of the blade drive can help resolve this issue.

6. Why is my beard not sharp?

A beard that feels prickly or not sharp is often a sign of dryness. Applying hydrating products like beard oil, balm, or shampoo can help reduce prickliness and scratchiness. These products provide moisture to the beard, making it softer and more manageable.

7. Can electric trimmers be sharpened?

Yes, electric trimmer blades can be sharpened. It is recommended to sharpen hedge trimmer blades regularly using a flat file and a whetstone. If you're not confident in sharpening the blades yourself, you can also take them to a professional or the manufacturer for sharpening.
