Lawn care is something you have to do if you have a yard. Now, if you have some soap in one hand and a lawnmower in the other, it can be a nice way to get some sun. Nothing smells better than grass that has just been cut. Grass can only be cut well if the mower blades are sharp, of course. Ever try to cut your lawn with blades that aren’t sharp? Not only do the blunted edges not do the job, but they also leave clumps of grass that get stuck in your mower.
The answer is easy: sharpeners for lawn mower blades. These important tools help keep your lawn mower’s blades as sharp as possible. Power drills have both manual and rotating heads that can be added.
The best tools for sharpening lawn mower blades work quickly, can be used more than once, and match the style of your mower. This list shows you the best sharpeners and tells you everything you need to know about this important piece of lawn care equipment. Let’s go over the choices.

It is thicker than most other grinding wheels because it is almost an inch thick.
Since corundum doesn’t make a lot of dust, you can do the sharpening job inside or outside. With a cutting angle of 25 degrees at the edge of the stone, it fits evenly on the surface of the blade. This makes it easy to sharpen any kind of lawn mower blade quickly.
It’s important to remember that these won’t last forever. The point of connection gets worse after each use, which means it works less well each time you sharpen. The good news is that the set comes with four sharpeners, so it should last at least a whole season.

Best Lawn Mower Blade Sharpeners Buying Guide & FAQ
If you want a lawnmower blade sharpener that works and lasts, there are a few things you should look out for. The first step is to decide what you want the sharpener to do for you. Will you use it for more than one tool in the garage? Or do you plan to use it with your push mower and nothing else?
How you choose the right tool comes down to what you want to get out of it. Once you know what you want from the sharpener, you can make your search more specific. As long as it is made of good materials and has a design that is easy to use, you are well on your way. The most important thing is to find a sharpener that works well for your needs.
How Having a Lawn Mower Blade Sharpener Can Help You
Everyone who owns a lawn mower needs a tool to sharpen the blades. Imagine trying to cook with a dull knife. It would be dangerous and annoying. The same thing goes for your lawn mower. If it can’t cut through the grass well, things will get messy fast. A blunt edge won’t cut the grass, but it will damage it. This lets the water out, which makes the grass grow in clumps. You also have to clean the mower more often and use more gas to get the job done. A lawn mower blade sharpener helps you do the job right the first time and keeps you from having to buy new blades.
Plus, there’s no rule that says a lawn mower blade sharpener can only be used on a lawn mower. Sharpeners can be used in a lot of different ways. Sharpening things evenly is useful for everything from hunting knives to kitchen tools. A good sharpener makes your tools last longer by smoothing out the surface evenly. It also makes it less likely that a dull or broken edge will hurt someone. There are a lot of good reasons to keep these tools around. They are easy to store and can do a lot of different things.
- It helps your lawn mower work better and use less fuel.
- It is available in different formats that can be used by hand or by computer.
- Slows down the wear and tear on the blades of the lawn mower.
- Any size or type of blade can be sharpened with the right tool.
- The overall utility value is increased by the many ways that sharpening can be used.
- Tools that last and don’t take up much space in the garage.
- Works with the power drills or grinders you already have to sharpen tools.
Types of Tools for Sharpening Lawn Mower Blades
The goal of every tool that sharpens lawn mower blades is the same: to get rid of the flaws on the side of the blade and make it sharp and smooth. This is done in a different way by each type of blade sharpener. Some are made to be used with analog tools, while others use power tools that you probably already have.
All of the different types have their good points, and each one is better for different situations. If you have a big yard and use a ride-on mower, you won’t want to file your mower blades by hand. On the other hand, if you’re just cutting a small patch of grass outside a condo with a small push mower, it doesn’t make sense to go all out with a power tool.
When choosing the right blade sharpener, think about how often you will use it and make sure it will be easy to store.
These files are best for small grassy areas and people who like to keep things simple. They have an advantage because they can be used to sharpen knives and other tools around the house. It will take more work (and more time) than other choices, but it also has some advantages. You have complete control over the results, it’s as environmentally friendly as you can get, and it still gets the job done.
Of course, if it was perfect, they wouldn’t have made any other kinds. Using portable files takes more time. At least 30 pulls across each side of the blade will do the trick. Even though it doesn’t take a lot of strength, 30 reps of anything add up. Also, the results may not be as good as with powered models. Handheld sharpeners are great for small areas but a nightmare for larger yards.
Next, we have drill attachments that can be attached to any drill with a quarter-inch hex. These are made of beveled corundum and come with a guide that helps you put them in the right place. Depending on the angle of the blade, it spins quickly to make the blade smooth. If you want to work quickly, you’ll need more time to set up but much less time to apply.
One downside is that it’s easy for a beginner to overdo it, which can throw off the balance. Angle grinders are less likely to hurt the user, so drill types are better for more experienced users.
Angle grinders might cost a bit more than other options, but many landscapers prefer them because of how well they work. These hand-held tools have a disc that spins and is connected to the edge of the blade at an angle that you can control with your hand. Many even have more than one handle so you can get the right mix of speed and control. Most are powered by an AC cord, but there are some that use rechargeable batteries.
These are best for commercial use because they can fix mower blades quickly. Most of the time, the results are even, and the shape of the disc makes it less likely that it will damage the lawn mower blade. As long as you have a separate disc, you can use the same tool to sharpen more than one thing. Angle grinders are great because they can be used for everything from building to working with metal. If you don’t already have an angle grinder, you should get one because it can be used for so many things.
What to Think About When Buying a Blade Sharpener for a Lawn Mower
There are a few things to keep in mind when picking the best lawn mower blade sharpener. The first is how well it works. The point of a sharpener is to get a blade’s edge as sharp as possible. Precision is important, especially if you plan to use this on your lawn edger as well.
Next, you should think about how easy it is to use. Even though a drill attachment blade sharpener works well, it is much less useful if you won’t near a power source. Also, it won’t work at all if you don’t use a drill. Make sure you pick a sharpener that will work for your needs.
Lastly, you should think about how long you think the sharpener will last. Even though everything wears out over time, some sharpeners last longer than others. Most of the time, hand-held options last longer (though they are harder to use). If you want to use the sharpener on other tools, such as your pole saw or other blades, think about the extra strain and choose something that will last.
Lawn mower blade sharpeners’ most important features
By looking at how each part of a tool works, you can get a better idea of how well it will do its job. Just like how you can tell if your bench grinder or miter saw is working, a tool only works when all of its parts work together.
Instead of looking at the tool as a whole, look at each part individually first. These important parts give you a good idea of how good the sharpener is. When each part of a product is well-made, it’s easier to trust it. If you know what kind of sharpener you need, the features will tell you if it works or not.
The sharpening material is the grit that wears down the blade’s metal. Different materials are used for different types of sharpeners. But carbide and corundum are the two main things that are used in blade sharpeners. Both of these things are harder than the metal in the blades, so they work well to sharpen them.
Sharpeners for drills often use corundum. This aluminum oxide is very hard, which gives it the strength it needs to smooth down the blade’s edges. Carbide is a metal that has a lot of carbon in it. Its molecular structure makes it strong enough to work as a sharpener. This is more common in sharpeners you hold in your hand.
Method of Sharpening
The way a sharp edge is made is what this feature is talking about. This is pretty easy to do with drill attachments. Attached to the drill, the sharpener uses the drill’s motor to grind down the surface. The balance of the sharpener gets better over time if there are two layers of stone.
Sharpeners that you hold in your hand work differently. Some have a hole where the blade can be pulled through easily. This takes away the sides evenly and gives you a sharp edge. When using a handheld model, it’s important to make sure the blade fits the sharpener’s shape. As long as it does, this feature can give you sharpening results that are very even.
How to Sharpen a Lawn Mower Blade
At first, glance, sharpening lawn mower blades might look hard, but it’s actually pretty easy if you have the right tools. Details will depend on the type of lawn mower you use. For example, a ride-on mower will be different from a push mower. Even though there are differences, the main points are still the same.
The first thing you need to do is set up your workspace and tools. Have your sharpening tools and a power source on hand, if yours is electric. Make sure you have the right gloves to work with and safety glasses to protect your eyes. You may need hearing protection, depending on how loud your lawn mower blade sharpener is. Lastly, make sure you have a set of adjustable wrenches for the next step, which is to take off the blades.
Taking the Blades Off
Make sure the mower is turned off and unplugged from its power source. To avoid spills, empty the gas tank. Make sure the filter and carburetor are facing up by laying the mower on its side. A good idea is to put a mark on the bottom of the blade (it will be useful later). Find the nut that holds the blade in place on the unit. Turn it until the blade comes loose. It will probably have dry grass and dirt on it, so you will need to clean it first.
Spruce up the Blades
Now that your blades are separated, you can move on to the next step. To clean the surface, use a dry cloth. If the dirt is more stuck to the blade, you can use WD-40 or another lubricant. Make sure you give it the right amount of time to set before moving on. Once the surface is clean and dry, it can be sharpened.
Sharpening: Files, Grinders, and Drills
Step one of sharpening is to hold the blade in a certain way. Put it in place with a vise grip. Make sure that the blade’s cutting edge is facing up. Check for any dents or cracks and make sure sharpening is better than replacing them. Now that you’re ready, you take your tool of choice and get to work.
Put the sharpener on top of the blade’s cutting edge. Only move the file in one direction, or “with the grain.” Back and forth motion can result in damage to the blade (and the sharpener) (and the sharpener). When you move the sharpener, you will likely feel protrusions on the blade. This tells you that you’re applying the right amount of pressure. Otherwise, use a bit more force. Move the sharpener along the blade’s angled edge. Most of the time, you won’t need more than 50 file strokes to finish the job. Once you’re smoothed out all the rough patches, flip it over and repeat the process on the other edge.
Gloves and eye protection are needed when using power tools. Follow the same steps for clamping as you would with the manual method. Attachments for standard drills have a quarter-inch shank and come with a guide piece. The beveled side lets you sharpen at the right angle. Connect it to your drill, turn it on (or plug it in), and place the guide against the back of the blade. The blade’s edge should fit into the bevel, which will give you the right angle for sharpening. Run the sharpener over the blade with light to medium pressure. Each side shouldn’t need more than two passes.
Most professionals like this way of sharpening because it is easy and works well. Clamp the blade the same way you would for other ways to sharpen it. Put a flap disc on your angle grinder. This piece is part of a lot of sets. Align the cutting edge of the grinder blade with the edge of the mower blade. Move the grinder back and forth while putting very little pressure on it. To smooth out rough spots, follow the angle of the blade’s edge.
Keeping the Blades in Check
The blade needs to be balanced, which is an important step that is often overlooked. If the blade isn’t sharpened evenly, one side can get lighter than the other. This hurts the mower’s performance by making it wobble. It also causes vibrations that damage the mower itself. Use a screwdriver and hold it so that the blade is balanced on the handle. It should stay where it is, and if it moves down in one direction or the other, you should sharpen the difference until it is even.
Putting the blades back on
The last thing to do is to put the blade back on the lawn mower. Clean up the area around it and get rid of any trash or grass that has stuck to it. Look at the blade and find the mark you made when you took it off earlier. Put the blade on the bolt in the right way and tighten it with a socket wrench. Make sure the blade is in place well. Put the electrical parts back together. If it runs on gasoline, fill up the tank.
Start to mow
After a quick check to make sure the mower starts, run it over a small patch of grass to make sure everything works. It should be easy to cut and cut evenly. As long as it does, you should have enough fuel to mow for 20 hours. It usually means that the blades need to be sharpened at least twice a year. But after you’ve done it once, you can do it with your eyes closed (but don’t). By making sharpening a regular part of lawn care, you can get a better-looking lawn and avoid having to buy new blades.
Best Lawn Mower Blade Sharpeners FAQ:
Landscaping is a big part of a home’s value, so it makes sense to take better care of your lawn. That means you have to ask questions and keep up with new technology and developments. The whole point is to give you a well-kept lawn without having to deal with blades that are dull. Every yard is different, so it’s important to learn how these sharpeners work in order to do the job right.
How can I tell if the blade on my lawn mower needs to be sharpened?
The lawn will be the first sign. If the grass looks uneven after you mow, you should check the blades. Another sign is if the grass looks bent or crushed. Look at the blades and make sure the edges are sharp. If they are dull, they need to be sharpened.
Can the blade of a lawnmower be too sharp?
Mower blades can be too sharp, that’s true. First of all, you don’t want to touch them because you might cut your finger. Also, if the metal is that thin, and it hits a pebble, the blade’s structure will be broken. You can hurt the blade if you use it too much. Take it slow to keep your blades working longer.
Q: Is a lawnmower blade sharpened on both sides?
You make the blade’s cutting edge sharp. Some lawnmowers have blades that only cut on one side, while others have blades with a point. If you’re not sure, take a look at how the blades are made. If not, find the side that cuts and sharpen it.
How can I sharpen the blade on my lawn mower?
Either a hand tool or a power tool can be used. Angle grinders and hand files are two common ways to do this. The first is strong and makes blades sharp quickly. It does need electricity, though. Hand files are harder to use, but they are more useful because they can also be used to sharpen knives and other tools.
Q: Can a lawn mower blade be sharpened without taking it off?
Some sharpeners for lawn mower blades let you do a quick job without taking the blades off. Remember that when you take the blades off to sharpen them, the results will be more even and last longer. If you don’t take the blades off, they’re more likely to get damaged when you sharpen them.
How much does it cost to sharpen the blade on a lawn mower?
Getting it done by a pro could cost $100 or more. It will save you a lot of money to do the job yourself. Not even the most expensive sharpener will cost more than $20.
How should a sharp mower blade be angled?
For the best results, the blade of your lawn mower should be at a 45-degree angle.
How often should I sharpen the blade on my lawn mower?
Every 20 hours of use is a good time to sharpen your blades.
