How To Sharpen Loppers With Easy-To-Follow Steps

Well, gardeners live and breathe their plants, and keeping the plants healthy and flourished is their priority. So smooth pruning is a must to remove dead parts and support growth.

But this task is only well done when you use a sharp pruner—no more waiting. Let’s discover the methods on how to sharpen garden loppers.

A Kick-start Before Sharpening

Cleansing The Blade

When lopper blades are not used for an extended period, it builds up dust and sticky gunk that hardens over time, causing joints to become stuck together and the tools to become unusable.

Cleaning the blade’s surface eliminates all of the extra dirt and the gunk lump from the plant sap, allowing the sharpening process to go smoothly.

Get a basin filled up with warm water mixed with dish soap and a small brush or scrubbing sponge, as preferred.

Scrubbing the soapy water on the surface dissolves the adhering on the blade. You may use the same procedure to any other tool that has sticky things on them.

Rusted-Removed Treatment For The Blade

A rusted blade is not sharp enough to make clean cuts, thus slowing down the healing process. Not to mention, the rusty surface carries a ton of bacteria, making the plants prone to diseases.

Powerful and effective chemicals will be a solution for small tools, but they will need time. If you prefer handcraft remedies, use abrasive tools such as screwdrivers to scrape off the rust and then smooth it with sandpaper.

However, if you’re searching for some do-it-yourself alternatives, you may utilize items you already have in your kitchen. The simplest method is to soak the tool in white vinegar.

You may also use baking soda or a salt and lemon mixture instead of white vinegar. Allow the mixture to settle for a few minutes before scrubbing it down to eliminate the rust thoroughly.

Finally, make sure the blade is pristine after cleaning it, and you’re ready to go on to the following session of the lopper sharpening process.

Two Excellent Tools To Sharpen Loppers

Loppers Sharpening With A File

Step 1: Tighten the lopper on a vice

Firstly, tighten the lopper blades firmly on a vice to prevent unexpected movement while performing the sharpening process.

Adjust the direction of the sharp edge of the blade pointing towards you to get the ideal angle to start sharpening.

Step 2: Marching the blade with the file

Align the file with the length of the cutting edge by holding it at a shallow angle.

Move the file across the edge without scraping it back. Otherwise, it will diminish rather than improve the sharpness of the blade.

You may need to strike the blade many times to get the ideal sharpness. Over-sharpening, on the other hand, may result in the blade snapping.

Step 3: Another go with the other blade

The majority of loppers are composed of 2 blades joined together. When you’re finished with the first one, because the cutting edge alignment of these two is distinct, you have to file it on the opposite side for the second one.

Grind Your Lopper With A Whetstone

Step 1: Apply for protection on the whetstone

In this procedure, we will use a whetstone as a garden tool sharpener. Before beginning, smooth the stone’s surface with lubricating oil to avoid the heat from flaring up and the excess heat leaking out when sharpening the blade.

Step 2: Put the lopper sharpener into work

Take a look at your blade and identify the beveled edge; we’ll start there. If the tool is an anvil-style lopper with a single blade, sharpen both sides of the blade. For bypass loppers, the effort you need will double up.

From here, place the bevel edge on the whetstone and begin working in delicate movements. Start to follow these smooth strokes in one direction a couple of times until the cutting blade’s luster is regenerated.

Some stones contain grit grades of coarse and fine on both sides. For the process to go perfectly, you should place your whetstones on a sturdy surface, preferably the ground.

If the blade has any nicks, remove them with an 8-inch-long fine-grit mill bastard file; a medium-grit file may be required to remove extensive or frequent nicks.

You don’t need to push or go overboard; just be nice and calm, and everything will go perfectly.

Step 3: Conceal the wrinkle edges

If things go beautifully in the last step, now you have had your cutting edge sharpen the lopper’s blade. Continue to sharpen your blade until it ultimately turns out as a razor-sharp cutting edge.

This process, meanwhile, may render your blades more brittle and minimize potential damages when cutting repeatedly.

When the cutting edge seems crisp and polished, it has most likely been sharpened sufficiently. Lift it to the background light. If the light bounces off the edge, your blade has been rejuvenated.


We have picked some of the most straightforward but most efficient techniques to sharpen loppers to help you prune your plants smoothly.
