How To Choose The Best File For Lawn Mower Blades

A metal file is an element that deserves to be present for many projects and jobs. The trick is to find the one that will get the most out of it or the set that ensures the project is done efficiently. We’ve looked at some of our favorite options above, but we still want to give you a few more tips on what to look for in a quality file.

When it comes to finding a suitable metal file, there are a few things to consider when making your purchase. Check out the tips below to get the most out of your investment!


Material counts in two ways. First, make sure your file is hardened carbon steel to last long. Second, you also need to consider the type of material you will need to file. For example, metal may need to be filed regularly, but sometimes you’ll need something that works with plastic or glass.


Metal files come in many varieties of shapes. They can be round, square, pointed, semi-circular, and more. The objector project you are working on will determine the shape you need.


Size is just as critical as shape. If you work with jewelry regularly, you’ll need files much smaller than a plumber’s metal files. The size will also determine the weight, making a difference in ease of use and comfort.


Speaking of comfort, you want to select an option that has a comfortable handle or fits the handle of your choice. Not all files are distributed with a handle, as they can be swapped with others if multiple files are used.

Margin of safety

This aspect is essential for many projects. It is the smooth, flat part of a flat-file. This is important if you work on a surface adjacent to an untouchable surface. It protects the surface you don’t want to file on.


The teeth are probably an essential aspect of your file. There are different types of teeth depending on your needs; also, keep in mind that the bigger the file, the lesser teeth it will have. This implies that the more prolonged it is, the more coarse it will be. Let’s dive deeper into the teeth and cuts below.

How to Choose the Best File For Lawn Mower Blades

Essential Things to Distinguish About Metal File Cuts And Teeth

The larger the file, the lesser teeth per inch it possesses, which will affect a coarser cut. The fineness of the teeth is called the cut of the file. The cut is classified according to the American standard or the Swiss standard.

For this article, however, we’ll be looking at the six most popular cuts of both classes:

  • Middle
  • Rough
  • Bastard
  • Second cut
  • Dead smooth
  • Smooth

Keep in mind that these files vary from thick to soft, but their length also plays a role. For example, an 8-inch file will be rougher than an average 6-inch cut file.

Files also come in a double or single cut. A solo cut possesses a single row of teeth equivalent to each other, while a dual cut has an extra set of teeth that intersect with a single set. You will find that many files have a single cut on one side and a double cut on the other side.

Unique cuts are also available for specific jobs. Here are some examples of popular specialty teeth:

  • Vixen Cut: Vixen files are ideal for the autobody. They have curved, shaped teeth that run straight down the face of the file.
  • Shear Cut: It possesses a single cut that intersects serrated teeth. They can be used to roughen the surface and smooth it simultaneously.
  • Maxi-Sharp Cut – This file has unique teeth that taper at the tip. Many people like this file because it can be used differently depending on how much pressure you use.

There are many other types of cut files. Combine it with different shapes and sizes; there is a metal file for almost any project you may have.

How To Sharpen A Lawnmower With A File

Professional landscapers and gardeners will tell you that the best tool for sharpening your mower blade is a file. It offers smooth, sharp edges, perfect for cutting and leveling bushes and grass. Here is a simple guide on how to sharpen a reel mower with a file.

First, disconnect the spark plug wire from the damper to prevent accidental engine starting or electric shock when removing the blade. To prevent gasoline and oil from entering the air filter and carburetor, turn the mower to one side with the carburetor and air filter up. When oil enters the air filter, the mower produces a cloud of smoke when the engine starts.

After placing the machine on its side, remove the blade to be sharpened by loosening the screw/nut that secures the blade. Turn screw and blade counterclockwise until removed. Return the knife to the cutting position after removing the blade until sharpening is complete.

Hold the blade firmly and start sharpening the edge with a high-quality file sharpener, file in the direction of the original cutting angle. File until the blade is sharp. Always remember to sharpen blades on top of the cutting edge. Sharpening both sides of the blade reduces blade life.

Balance it with a recommended blade balancer once you have finished sharpening the blade. Unbalanced blades often cause unwanted vibrations and can damage the mower’s motor. Replace the blade and firmly tighten the screw on the cutter.

Do you sharpen both sides of a lawnmower blade?

Although sharpening both sides of the mower blade is not harmful, it shortens the life of the blades. Therefore, it is recommended to sharpen the blade from the side.

How to sharpen a mulching lawnmower with a file?

Sharpening a mulch lawn mower follows the same procedure as sharpening a regular lawnmower with a file. The only difference is that a chipper blade has curved/curved edges. Just pick up the file and refine the blades until they are smooth and sharp. A tapered file permits you to refine edges that a big flat grit cannot.

How often should lawn mowers be sharpened?

The sharpness of lawnmowers depends on how often the blades are used for mowing. The most commonly used blades tend to dull and become unbalanced faster than those that cut occasionally. However, it is recommended to sharpen the cutter blade after 30 hours of use.


If you’re looking for a long-lasting file that consistently delivers a smooth, refined edge to your lawnmower, the Corona FE405510BC1CD Mill Bastard Cut File is a preferred option. The file is abrasion and corrosion-resistant, thanks to the chrome used.
