Best Edger Blades to Buy In 2021 [Review & Guide]


For the inexperienced ones, lawn care probably starts and ends with weeding, raking, and mowing. Although these are very important, lawn edging should also be practiced.

Edging refers to the maintenance of the edges of your lawn that spill onto walkways and driveways, creating a thin yet noticeable strip of grass. Getting rid of that is what constitutes edging. You can enlist a professional’s help to do it, or you can do it yourself with an edger.

Even if you have a good lawn edger, though, its performance will ultimately only be as good as its blade. The best edger blades not only allow for a smoother edging experience but can be sharpened more times, so a replacement will be needed later rather than sooner.

In today’s article, we’ve rounded up 5 of the best blades for your edger. Let’s get started!

Buying Guide for Best Edger Blades

Your edger is only as good as your blade. So, remember to keep the following factors in mind before choosing one for yourself.

Compatibility

First and foremost is the consideration of whether your selected blade is compatible with your edger. Otherwise, there would be no point! Look out for an easy-to-mount attachment point, and make sure that the blade isn’t too heavy for your edger.

Although most blades are compatible with most edgers, note that some manufacturers enable their edgers to be compatible only with blades from the same manufacturer.

Blade Type

Blades for edgers come in different types to suit different purposes. Let’s have a look at each blade type in detail.

  • Flat Blade

Sporting a rectangular shape, flat blades are characterized by sharp edges on opposite corners. These are preferred for simpler edging operations, e.g., when working on a lawn that sits level with a walkway.

One drawback of flat edger blades is that they don’t offer much maneuverability. Rotating them through tough terrain is difficult, so your best bet is to use a flat blade with an electric/gas-powered edger.

  • Scoop-Cut Flat Blade

A variation of the flat blade features scooped ends. These scooped ends do a better job of digging through soil covers, so if there’s some edging, you need to get done alongside flower beds, this is the kind of blade you should go for. Keep the grass from reaching into your precious flowerbeds!

  • Star-Shaped Blades

This blade is usually characterized by 8 sharp points, although this can vary according to the blade’s intended purpose. If your lawn is positioned beside a solid barrier like a wall, then a star-shaped blade will be the right fit for you. You’ll also appreciate them if you’re working with shrubbery/hedges along a paved walkway.

Durability/Build

When it comes to the durability of any kind of blade, you’re not only considering how long it will last, but how long it will be able to perform consistently. The thickness of the blade usually determines its durability. Also, look out for high-quality carbon steel construction that has been blackened and tempered. Otherwise, it won’t be able to stand up to corrosion.

Efficiency

The efficiency of your blade will be determined mainly by its sharpness. Although it’s impossible to guess just how long a blade will retain its sharpness, you can also look into whether it would take kindly to being re-sharpened. Some blades might perform very well initially but lose their edge after being re-sharpened.

Frequently Asked Questions (FAQs):

What is Lawn Edging, and Why Do I Need to Do it?

As the name suggests, edging is the process of manicuring the edges of your lawn. Beyond the aesthetic value of doing so, it also makes trimming and mowing easier. It's also used to separate landscape sections. You don’t necessarily have to do it yourself; most commercial lawn care packages include it.

How Do I know When to Replace my Edger Blade?

In new condition, an edger blade typically measures between 8 and 10 inches in length. This usually means that you'll be able to use it successfully for an entire season; however, with more frequent use, the blade will reach half its original size faster, leading to lower performance. Replace it then.

What's the Best Way to Take Care of Edger Blades?

Pressure/power washing is the easiest way to clean an edger blade. After doing so, you'll have to dry the blade by wiping it, preferably with a drying cloth made of chamois. Additionally, after every 3-4 uses of the blade, remember to coat it with oil.

Final Words

It’s undoubtedly unwise to expect a good performance from your edger unless you equip it with the best edger blades. We hope that you have found a worthy blade from amongst our picks; just remember to double-check for compatibility!

May your lawn always stay in tip-top shape with its edges cut neatly. Good luck!
