Let’s get to work.

1. Remove the Debris

Use a blade cleaning brush to remove any hair, dirt, or debris that may have accumulated. Closely check the nooks and crevices of the blades to ensure a clean surface for sharpening.

You can also use blade wash if the blade of the Oster trimmer  is more dirty. By doing this, you can easily clean it.

2. Sharpen with Stone

If you prefer a hands-on approach, manual sharpening with a sharpening stone can be effective.

  • Place the sharpening stone on a stable surface or secure it in a sharpening stone holder.
  • Apply a few drops of honing oil to the stone and spread it evenly.
  • Hold the clipper blade at the desired sharpening angle and glide it across the stone in smooth, consistent motions.
  • Use moderate pressure and maintain a steady angle throughout the process.
  • Repeat the motion on both sides of the blade, ensuring equal sharpening.

3. Testing the Sharpness of the Blades

Visually inspect the clipper blades for any visible signs of sharpness. Look for a clean and well-defined cutting edge along the entire length of the blade. Try cutting through paper, fabric, or hair samples.

4. Wipe off the Blade

After sharpening your blade to perfection, give it a final touch by wiping it down with a clean cloth. This step removes any remaining dust or debris and adds a brilliant shine to your blades.

5. Put the Blades Together

Once reassembled, don’t forget to apply a thin layer of oil to reduce friction and promote smooth operation.
