Different Tools Used For Lawn Mower Blade Sharpening

If you’re looking to add some new life to your dull blades, it may help to know a few different tools that are available for you to use on them.

You’ll be surprised at how much attention and care should be put into sharpening just one blade.

One of the most significant factors in deterioration comes from poor maintenance of blades, so this is something that should be taken seriously when you’re looking to repair or sharpen them.

Let’s look at a few different types of electric and manual blade sharpeners, which are recommended for both home and professional use.

Carbide Sharpener

First off, carbide blade sharpeners are one of the most popular tools among homeowners. This is a perfect choice if you’re just getting started with lawn mower maintenance or if you require light to medium maintenance work.

A carbide sharpener can make the job much easier and take care of the sharpening process right at home without the need for special skills or complicated processes.

Carbide sharpening tools utilize either a single or double set of tungsten carbide inserts within the hardened steel handle.

These inserts produce numerous microscopic scratches on the blade’s surface to sharpen or remove scratches and dents from worn blades.

This tool is also relatively cheaper yet gives you great value for your money. However, be careful you don’t overdo it.

Carbide tools are very aggressive and will take off more than you initially planned. Carbide inserts also dull quickly, and once that happens, they take off inconsistent amounts of material or none at all.

Stone Grinders

Using stone grinders is one of the most common and essential tools for sharpening lawnmower blades. It is a cheap and easy-to-use tool.

The surface of a stone grinder is abrasive enough to remove metal from the blade without drawing too much material at once.

The cover has a bed of tiny abrasive particles that file away metal with each swipe across the blade.

If you prefer an inexpensive and manual-operated sharpening tool but are afraid of the aggressiveness of carbide sharpeners, then go for stone grinders instead.

The stone grinder can sharpen a blade more precisely than a carbide sharpener. However, it takes more time, and the stone can become uneven after long periods of use.

Electric Blade Sharpener

An electric sharpener is a staple for many severe landscapers, and professional gardeners as this tool are easy to use and extremely helpful in sharpening lawnmower blades.

If you want to pass on the energy-consuming process of manually sharpening blades and if you’re willing to invest in a machine that makes blade sharpening easy, then an electric sharpener is for you.

It handles all of the work faster than any manual tool can and will be able to restore your mower blades time and time again.

There are numerous concrete benefits of electric blade sharpeners.

They are much easier and less time-consuming to use than other sharpening tools, faster yet more accurate when compared to manual blade sharpeners, and can be used on almost any kind of garden tool needing sharpening.

We’ve taken a look at all the different tools that you can use to sharpen your lawnmower blades.

Whether you prefer a carbide sharpener, stone grinders, or an electric blade sharpener, the following list will present you with the best sharpening tools for a lawnmower that is currently available in the market.

Things to Consider Before Buying Blade Sharpening Tools

Power Type

As mentioned earlier, blade sharpening tools are either manually operated or electric powered.

The main difference between these two types of sharpening tools is that the electric machine can handle more work with minimal effort.

At the same time, manual equipment must be operated with greater precision and attention to detail.

Note that an electric sharpener uses power from batteries or electricity, generally attached to the sharpening head.

When you run out of juice, the device will stop functioning until you replace the battery or plug it into an outlet.

On the other hand, a manual sharpener only requires labor and effort to enable operation but requires a lot of careful and precise adjustment of angles and blades.

Also, a manual blade sharpener is a more affordable option than electric ones, so it boils down to your preferences and needs.


Regardless of which brand or style you choose to go for, it is essential to ensure you get a sharpener that works with your specific lawnmower blade.

Buying the wrong one could cause a lot of frustration and even damages, so make sure you do some research about the technical aspects of your lawnmower before choosing a sharpener.

To check for compatibility, simply check the size of your blade in inches and make sure the blade sharpener accommodates your lawnmower’s blade size.

Doing this ensures compatibility and optimal performance of the sharpener while preventing damage to your blades.

How to select blade sharpening tools

Quality and Durability

When choosing sharpening tools, you want to look for high-quality products with top-notch performance.

The quality of your blade sharpening tools is crucial. Using poor-quality tools can lead to blades becoming nicked and damaged instead of sharp and jagged.

To get a durable lawn mower blade sharpener, you need to choose the one with a robust construction that can handle lots of wear and tear while taking care of your mower blades.

Whether you are using carbide sharpening tools, stone grinders, electric blade sharpeners, or any other type of tool, remember to check the material and construction of the blades or stone to ensure that they can sharpen your blades without frequently replacing them.
