- Flat file
- Soft fabric

2. Start by Ensuring Safety Precautions
Before starting the actual process, make sure you have taken all important measurements for playing it safe. Wear safety clothing if possible. You want to never skip safety glasses and a hard pair of gloves.
This is a matter that involves blades, even if it’s not sharp. Also never forget the fact that dull blades are usually reason behind an accident more than sharper ones. Make sure you turn off the tool as well, double-check if necessary. Because things will get really messed up if the tool suddenly starts in between of this sharpening process.

3.Give the Teeth a Good Cleaning
Your hedge trimmer’s cutting component, aka the teeth, goes through a lot when dealing with plant sap and resin. This stuff gets accumulated with the nasty stuffs, which eventually is one of many reasons behind its dullness.
Make sure you use a soft fabric to thoroughly clean any unwanted stuff out of the teeth. Simply use your glove worn hands to hold the hedge trimmer on a workbench. And then use the cloth to wipe the areas gradually focusing on removing all dirt. This should be your first step towards a get a good result with sharpening later on.
4.Time to Sharpen Using the Flat File
Now focusing on the cutting edge, use a flat file to sharpen. This sharpening tool is designed to work with good results only when applied in one direction. So, you need to be careful about following the same direction while giving hedge trimmer this controlled sharpening session.
Another thing you need to do is checkup the operating instructions given on manual of your trimmer tool. Here you should be able to find the appropriate sharpening angle. Usually, it stays right under the technical data segment. When you are filing, use this recommended sharpening angle to get the best results. In some cases, you get results only by following the necessary angle requirement. So do pay attention to finding this proper information.
Now what do I mean by following one direction filing? Well, when you move the file back, make sure to lift it from surface. Because the file will only be effective with forwarding stroke in most cases. Don’t try to saw back and forth with the file. This will do the very opposite and possibly blunt cutting edge that you’re trying to sharpen.
The abrasion limit is usually not more than 5 mm. So, when you are sharpening, make sure not to remove too much material. This can later lead to badly impact the material’s strength and make it compromise its overall quality. And that’s not very good news for your hedge trimmer’s expected long-term usability.
With each cutting-edge tooth, you should maintain a similar number of filing strokes. There must be integrated cut protection. Make sure you don’t file this part accidentally.
5.Get Rid of The Burrs
Now for this particular step, you’ll need a good quality whetstone. During the filing process, there must be some burrs that got developed right on blade’s underside. You need to smooth these out using the whetstone tool.
To properly work on the blade backside, you need to turn over hedge trimmer. Keep on moistening it gradually and gently while this process. Use a slow and steady swiping motion to carefully draw the whetstone with each blade. The swiping motion should be in tips’ direction. This will help to get rid of any rough surface.
The hedge trimmer should be sharp by now. Now you need some aftercare for it to work flawlessly. The previous steps must have resulted in a lot of dust. You need to get rid of those grinding dust first of all. Then you need to think about reapplying the corrosion protection that might have got removed because of the filing process. Simply spray some resin solvent over the cutting apparatus. This will ensure the machine’s proper functioning and also make it servable for a long time.
