How to Sharpen Gardening Tools - Best Knife Sharpener

Gardening tools must be kept sharp in order to work well. Dull blades can cause damage to plants and grass by tearing as they occur, not to mention the extra effort you have to put into using them, which will make landscaping and gardening much less enjoyable.

Gardening tools should cut plants cleanly with very little force applied. If you start to apply force, the blunt edges may slip out and hurt you.

Don't push your garden tools too far before you sharpen them. It's always a good idea to give them a quick sharpen every time you use them so you don't have any problems.

You can sharpen your gardening tools in several different ways. The type of sharpener you use depends on the size and type of gardening tool you need to sharpen.

All of these methods take a fairly short amount of time.

The only reason it takes forever is if the blade is very dull, or if you use something small like a sharpening stone to sharpen a very large blade, such as a machine used to cut down large trees or dig up tree trunks.

How to Sharpen Garden Tools

There are five main types of gardening tool sharpeners that gardeners typically use.

You will find that a sharpening stone can be used to sharpen almost anything, but there are alternative tools that can be used for a faster and easier sharpening process. You can find all of these sharpening tools at any hardware store as well as online.

Sharpening stone

A whetstone is a long metal file used for many sharpening and crafting purposes. One of its uses is to act as a grinder for gardening tools.

If you are sharpening a fairly small tool, such as shears or a small spade, using a file should not take any more time than a grinder.

Large or extremely dull blades, however, will take more time. A miter file can sometimes do a better job because it gives you more control over the sharpening process, and you are less likely to damage the blade.

To use a miter file, you need to use both hands.

Place your writing hand on the handle of the file, with your less dominant hand pressed slightly against the top of the file itself, toward the tip. This gives you more control over the movement of the file.

After filing, apply lubricant to the gardening tool to prevent rusting.

Use a miter to file small gardening tools or lawn mower blades.

Angle Grinder

An angle grinder is a handheld grinder that has a round, textured disc that you can use to grind or sharpen objects, including garden tools such as shovels, garden hoes, axes, or lawnmower blades. When sharpening garden tools, make sure your disc is labeled "Grinding disc. For metal," or you will not be able to properly sharpen blades.

How to use an angle grinder to sharpen a spade.

Wear eye protection and take the necessary safety precautions.

Use pliers or a heavy object to hold the shovel in place for sharpening.

Set the angle grinder to a slow speed.

Turn on the grinder. Move across the edge of the shovel in a sweeping motion to grind it flat. Maintain a 30 degree angle for best results.

Benchtop Grinder

A bench grinder can be used to sharpen the same types of gardening tools as an angle grinder, but is less convenient. A bench grinder rests on a flat surface; it is not held in your hand like an angle grinder, so there is less mobility and control.

If you use a bench grinder correctly, you can still get a good edge on your blades with it. Unless you have very dull gardening tools, it's not typical to use a bench grinder to sharpen your knives. You can also use it to get nicks out of the surface of the blade.

How to sharpen a lawn mower blade with a bench grinder.

Using a bench grinder is simple. Place the mower blade on the grinder at the same angle as the existing bevel.

Move the blade so that it is sharpened evenly over its entire length. Continue sharpening until the blade is satisfactorily sharp.

A dull mower blade can damage your lawn by tearing and pulling at the ends of the grass. For regular maintenance, sharpen your mower blades with a sharpening file, but if a stone leaves large scratches or nicks in the blade, use a bench grinder again.

Sharpening stones

Sharpening stones are small and compact. Sometimes it is easier to hold a sharpening stone than to hold a file or grinder.

It's also easier to carry around. You can use it to sharpen knives, shears, hedge clippers and chisels.

Generally, it will not work well on larger blades, but there are some sharpening stones that contain diamonds that can be used. Diamond sharpening stones are much stronger and can last a long time without wearing out.
