Best Lawn Mower Blade Sharpener 2020 – Ultimate Guide and Reviews

On the site we’ve taken a look at some of the best lawn mowers for a small yard. (That article can be found here.)

But did you know it is incredibly important for the health of your grass, and yard, that your mower blade remain very sharp?

The most common solution to a dull blade is to get it professionally sharpened, or to replace the blade altogether.

We’ve taken a look through the many blade sharpeners available on Amazon and elsewhere, and we’ve compiled a list of 5 of the best options.

Keep reading for a full exploration of each sharpener, and to not only discover which sharpener works the best, but also which one is best suited for you!

The 4 Best Lawn Mower Blade Sharpeners For 2020

Creative Sales Company Lawn Mower and Garden Tool Sharpener

About the Creative Sales Sharpener

The first sharpener we’ll take a look at is the Creative Sales Sharpener.

This sharpener is an American-made, handheld tool, used manually to sharpen mower blades.

There isn’t much to this device – essentially you would remove your mower blade and drag this sharpener along the blade’s edges until it is adequately sharp.

Mower Blade Sharpener

For a small, cheap-looking device it is actually surprisingly well-built, and decent enough at sharpening your blade.

It looks dangerous but it has a small hand-guard and you can move at your own pace.

It can also be used for other gardening tools which is a nice bonus.

Our Input

The Creative Sales Sharpener is very rudimentary.

It may require a little sweat to get a really sharp blade and might not be as effective if the blade has any serious bumps.

Overall, we’d recommend getting something a little quicker and more effective to use, but if you prefer to sharpen manually with an American-made product this is a decent choice!

Smith’s Mower Blade Sharpener

About the Smith’s Sharpener

The second manual sharpener we’d recommend is a little bit more durable of a tool.

The Smith’s Mower Blade Sharpener functions in pretty much the same way as the Creative Sales sharpener, but it has a larger hand grip, which allows for the use of gloves while holding.

Additionally, this sharpener comes with a wire cleaning brush which can come in handy for keeping the actual sharpener clean.

Our Input

If you’re looking for a manual sharpener, this one is much bigger than the Creative Sales device, and much sturdier too.

Don’t expect it to sharpen blades with ease though. After all, it is manual.

VintageBee 4 Pack Lawnmower Blade Sharpener

About the VintageBee Sharpener

The VintageBee 4 pack of blade sharpeners is a useful tool that can be attached to any power drill.

Commercial Mower Blade Sharpener

The nice thing about a drill attachment sharpener is that it removes the strain of manually sharpening your mower blade, and most homeowners have a drill of some kind laying around.

These sharpeners are useful for other devices too, such as shovels, shears, or other gardening tools.

The sharpeners are made out of Corundum, a material that is very durable and unlikely to chip or wear with time.

Our Input

This was the best deal for drill-attachment blade sharpeners we could find.

The VintageBee sharpeners will get the job done much easier than a manual sharpener, and they are a useful drill attachment for any toolbox.

We also looked at the Arnold BSK-1 Sharpeners, but we found that the blade balancer was obsolete, and the value of the VintageBee offering was better.

A blade balancer is a tool to ensure that both ends of the blade are equally sharp (ensuring a proportionate mow), and while a dedicated blade balancer is nice, it is not necessary.

A nail mounted on a wall serves as a perfectly fine balancer, simply place the blade on and further sharpen the side of the blade that is heavier until the blade hangs balanced.

Ultimately, the VintageBee sharpeners work just as well as the Arnold BSK-1’s and they come in a pack of 4 for a very comparable price!

This is our “Best Value Pick!”

Dremel A679-02 Attachment Kit for Sharpening Outdoor Gardening Tools

About the Dremel Attachment Sharpener

We’ll preface this review by noting that you must have a Dremel Rotary Tool in order to use this attachment.

The Dremel found here is a nice cordless option and is a great tool for any homeowner to have handy.

The Dremel A679-02 Attachment Kit is attachable to any Dremel rotary tool, and is the most intuitive, and useful sharpener we’ve found yet.

This sharpener is especially useful as it is very effective at sharpening and maintaining chainsaw blades (and other gardening tools) as well!

The sharpening tool maintains the edge at a consistent angle and will get a sharp edge from even the dullest, rustiest mower, chainsaw, or shear blades.

The kit also comes with three different sharpening stones. The pink stone is 7/32”, the 3/16”, and gray 5/32”, giving you the variability to sharpen many different kinds of tools to a few different levels.

Watch the video below for a quick walkthrough of how the tool works, as well as a quick demonstration of ensuring a balanced lawnmower blade!

Our Input

If you don’t have a Dremel rotary tool, then perhaps this isn’t the sharpener for you.

But we would highly recommend having a rotary tool present in the house, especially if you’re the type to tackle home repairs and fun construction projects yourself.

The Dremel gardening sharpener tool is extremely useful and will help to maintain your tools, and even get a much longer life out of them.

While this is definitely the most expensive option, it also is the option that provides the most utility and usefulness.

The Dremel A679-02 Attachment Kit is our “Best Overall” lawn mower blade sharpener, and in our opinion, a must-have for any homeowner!


Best Mower Blade Sharpener

A well-kept mower blade means a well-cut lawn, and a well-cut lawn is the first thing any visitor or passerby will see.

We know that a sharp lawnmower blade can mean the difference between healthy and green cut grass, and that ugly brown dying grass.

The most important component of a sharp lawnmower blade is maintenance, and we looked at some of the varying options available to the diligent mower owner.

While a manual sharpener can be useful, and requires no instruction on how to use, it will require many passes to ensure a super-sharp blade and is easily surpassed by attachment sharpeners when it comes to universal usefulness.

Professional Lawn Mower Blade Sharpener

We chose the VintageBee 4 Pack of Lawnmower Blade Sharpeners as the “Best Value Pick”, as 4 drill attachment sharpeners will last you quite a while, and VintageBee’s sharpeners are more than serviceable!

Lawn Mower Blades Sharpening Tools

However, our favourite sharpener was the Dremel Rotary Tool Attachment Kit for Outdoor Gardening tools.

The Dremel attachment kit was our pick for “Best Overall” sharpener, due to its multiple attachment heads, quick and easy use, and usefulness on many different outdoor tools (not just lawn mower blades)!

This review is best used alongside our review for “Best Lawn Mower for a Small Yard”, which can be found on the site here.

We hope that this review has shown that it doesn’t have to be difficult to sharpen your own mower blades and can actually save you a bunch of money in the long run. Finding the right blade sharpener for you can make that process even easier, and even more cost-effective.
