How to Sharpen Pruner Blades with a Carbide Sharpener
The carbide sharpener is a handy tool to sharpen your bypass pruner blades. Basically, it’s a piece of carbide material that has been bonded to a handle and it’s very easy to use.
Using a Carbide Sharpener
First, run the carbide over the cutting blade (from the back of the blade to the tip of the blade) several times. Be careful to hold the sharpener at the angle that was originally machined into the blade at the factory.
Then, remove the burr from the back of the cutting blade by running the carbide from the back of the blade to the tip (one stroke only). Make sure in the burr removal process that the carbide stays flat against the blade, not angled in any way.
Use the same technique on the counter blade to make sure it’s also nice and sharp.
Believe it or not, doing this will restore the cutting blade to its factory sharpness (or close to it).

Which Carbide Sharpener To Use
I use the Corona SolidCARBIDE AC 8300. It’s an excellent tool and can not only be used to sharpen your bypass pruners but can also be used to sharpen loppers, shovels, axes, etc. (it won’t sharpen saw blades).
The Corona AC 8300 sharpening tool is available on Amazon and on the Corona website.
