To make your life easier, we’ve selected the 10 best lawn mower blade sharpeners sold on Amazon that can sharpen your blades to perfection and improve your mower performance and durability.

Finally, we’ll also check out some of the key things you need to consider when purchasing a blade sharpener as well as advice on how to sharpen your blades.

Read on!

What Kind of Power Type Sharpeners Use?

There are two types of sharpeners when it comes to the way they’re powered – they can either be electric or manual.

The first difference in the power source is obvious however, you might want to consider some additional features.

For instance, a manual sharpener is cheaper, but it requires hand labor to properly sharpen the blades. On the other hand, electrically powered sharpeners offer more efficient use without hand straining and they’re usually a bit more expensive.

Whichever you choose depends on how often you use it and what type of blades you need to sharpen. We think that any option can do help you sharpen the blades and improve your lawn mower performance.

How to Ensure Blade & Sharpener Compatibility?

Different lawn mowers use different types and sizes of blades, so you must make sure they’re compatible, and ideally, you can use them for different types of blades, not just one type.

Don’t forget to check the size of the blade as well as the angle degree. The perfect sharpener must fit these numbers.

What about Durability?

The durability depends on the material that the sharpener is made of because it lowers the risk of damage and potential injuries. The ideal solution is to purchase a sharpener constructed with carbide or one that has good warranty options that can ensure the long-term.

How Important is The Spinning Speed?

When purchasing a lawn mower blade sharpener, you can check out the spinning speed of the sharpener to get a better idea of the performance it can offer. To check this, look for the RPM abbreviation since this number refers to the rounds per minute.

The higher the spinning speed number, the better the performance. The RPM options can vary from 1500 RPMs to 1750 RPMs. A good spinning speed can offer a smoother sharpening and improved mower performance.

How to Stay Safe?

Safety comes first when working with any gardening tool, but this is especially important when it comes to the lawn mower, blades, and sharpeners.

When handling lawn mower blades don’t forget to wear protective gloves and always remove the spark plug. If you don’t do this, you risk being injured and break your hand.

These are important steps to follow when changing the blade and the same goes for the sharpening part. Always wear protective gloves and be careful when handling blades.

Additionally, it’s important to understand whether the blade is good for sharpening or it needs a replacement.

After years of use, some blades are just done and need to be replaced, so if you try sharpening them you won’t get the desired result and you might think that it’s the sharpener’s fault – however, this isn’t the case.

When it comes to the actual process of sharpening, make sure you start from the top side of the cutting edge – by doing this, you ensure to have a long-lasting edge on the blade.
