Tree pruners grow dull gradually due to clipping tree branches, but mainly due to dirt exposure. Using worn pruner blades on a tree limb is like attempting to chop raw steak with a butter knife; it just does not work.
Fortunately, you can sharpen the pruner blades using a 6-inch metal file or a sharpening rod that progressively files away from the soft metal. Whether your tree pruners have serrated saw blades or smooth blades that clamp shut determines your strategy.
Importance of pruning a tree :
Pruning a tree without the correct equipment may be time-consuming and challenging. It includes a lot of hand cramping and several trips up and down your ladder. But if you acquire a tree pruner, you’ll be clipping the branches and leaves off your yard’s trees like an expert.
You may apply it all year long to keep your trees healthy and in good shape. Before beginning to prune, a gardener should consider several factors. First, make sure that you select a high-quality pruner with all the features you want. Look for a model with a steel cutting blade, a leather handle with a soft rubberized coating, and a comfortable ergonomic design.
What is a tree pruner?
A pruner is one of those garden equipment that every homeowner should have. It will assist you in getting the most out of your gardening efforts and make your life much more straightforward. A pruner can remove dead or damaged leaves from shrubs, bushes, fruit trees, etc.
It will also assist you in training your roses to grow stronger and produce a fuller, more stunning bloom. A pruner is just a small set of shears linked to a long handle. Some models also have a wire brush at the end of the handle to remove burrs and undesirable sticks and vines that may have grown up around the plant’s base.
How to Sharpen the Tree Pruner’s Blade?
Now, let’s discuss how to care for and keep your pruner in good operating order. To begin, sharpen the cutting blade every time you use it. This is especially true if the edge has gotten dull. Dull blades not only produce poor work, and sloppy labor is harmful. It may result in significant harm. Here’s how to sharpen the blade of a tree pruner.
Sharpening The Smooth Blades
- If required, use a wire brush and degreaser to clean the blades. Eliminate the blade from the pole’s end. Spread the blades apart and secure them in a vice. Scissor pruners feature two blades that must be sharpened, whereas anvil pruners have a single blade that clamps down on a flat surface.
- Align a 6″ metal file with the angle of the beveled blade edge. Stick to the factory-designed angle if just one side of the metal is inclined or beveled.
- Appear at the beginning of the angle and work your way down to the blade’s tip or very edge using the file. Execute 3 or 4 passes in quite the same direction with the file. Slide it from base to end to sharpen the blade, revealing clean metal and the honed edge.
- Rub the file over the reverse side of the blade a few times to remove any fine metal burrs. If you’re using scissor-style pruners, sharpen the second blade as well. Apply lubricating oil to the newly cut metal.
Saw Blade Sharpening
- Wipe any dirt and tree debris from the blades using a wire brush. Remove any oily buildup on the blades using a degreaser and a towel. Remove the pruner pole blades if possible so that the pole does not get in the way. On occasion, the head with the knives unscrews from the pole’s end.
- Clamp the blade with the serrated edge pointing up in a table vise.
- Insert a sharpening rod into the two-toothed groove. Move the rod ahead to file away the metal and sharpen the blade. Repeat three to six times more until a burr of coiled metal filings appears on the blade’s reverse side.
- Constantly adjust the sharpening rod and push it forward rather than back and forth between the saw teeth. Rep this procedure for all of the saw teeth.
- To eliminate burrs, rub the reverse side of the blade with a sharpening rod or a flat-file. Burrs should remove in one or two passes.
- Spray lubricating oil or an equivalent lubricant on the blade edges. This coating will keep the exposed metal from corroding.
How to Sharpen a Pole Pruner?
A pole pruner is a long-handled trimming tool that allows you to trim the tops of trees, tall shrubs, or spreading vines without climbing a ladder. It’s a terrific tool that may make your gardening activities much faster and more straightforward until the blades become dull.
In that situation, the pole pruner becomes so difficult to operate that you might as well attempt clipping branches and vines with your bare hands. Fortunately, a case of dull blades does not necessitate the disposal of your pruner. You can sharpen your pole pruner fast and simply in the comfort of your own home.
- Insert the Pruner into a Vice:
The first step in sharpening your pole pruner is to secure it so it doesn’t move while working on the edges. Place one of the pruner blades in a vice that is beveled or rounded edge up and clamp it securely, so it doesn’t slip and harm you while you’re working.
With the control rope, draw the pruner into an open position and knot one end to the end of the pruning pull to keep it open.
- Sharpen the Beveled Blade:
Take your metal file next. Set this at a 45 ° angle and start polishing the blade’s beveled edge. Make careful you hit the blade with the file repeatedly in a steady, continuous manner, only shifting your hand in one direction.
When you move the file back and forth, you texture the metal, making it duller and less efficient. For your protection, file in the opposite direction of your body. Make careful to strike the whole cutting surface, then quickly file the opposite end of the blade to ensure it is likewise smooth.
- Sharpen the Saw Blade
Sharpen the saw blade with a tiny, round metal file. When operating in this region, use caution since it is possible to slide and cut oneself on the saw teeth.
Each blade on the saw has both a rounded and a straight edge. Use the tiny metal file just on the rounded edges of the teeth, pressing the file forward in the same motion as step 2 and guiding the file away from your body.
- lubricate it
After sharpening the blades, apply metal-specific lubrication oil to all of the pole pruner’s joints.
- The Importance of Regular Maintenance
To keep your pole pruner in good operating order, you should do this procedure regularly. If you’re planning to do trimming, carry extra scissors with you out into the garden area to work on the blades without having to return to the workshop.
Why need do you need to sharpen a looper?
Unlike garden shears, which are meant to be used with both hands, loppers are designed with both hands, allowing the operator to use more power while cutting thick branches. Most garden loppers are razor-sharp when fresh, and trimming involves little effort.
However, even the greatest garden loppers may get dull or acquire nicks from cutting too hard branches with frequent use. They can also become clogged with tree sap, reducing their cutting effectiveness.
Don’t buy a new set of loppers simply because the blades are dulling. Instead, read the following instructions to learn how to sharpen loppers and get years more usage out of the same pair.
With the materials and tools shown below, sharpening garden shears, pruners, and loppers may be accomplished.
Before You Get Started
Sharpening lopping shears aren’t rugged, although they can be messy because of the lubrication required to clean the blades. Instead of sharpening just one pair of loppers and calling it a day, assemble your whole collection of pruning shears and loppers and point them all simultaneously.
This may change during the gardening season, but it’s critical to clean and sharpen blades before storing garden equipment for the winter to avoid rust and corrosion.
How to sharpen garden loopers?
STEP 1: Remove sap from tree and plant blades.
The ability to clear away plant liquids without harming the steel of the lopper blades is an important first step in learning how to sharpen garden equipment. In this scenario, washing the blades with soap and water is not the greatest option since moisture can cause some types of steel to rust.
When sharpening shears, pruners, or loppers, the easiest approach to clean the blades is to spray them with a dab of lubricant, such as WD-40, which quickly dissolves the gunk. The residue should then be rubbed away with 0000 steel wool.
STEP 2: Sharpen using the bevel angle.
Loppers and pruners have a sharpened blade edge that looks like an angled bevel when looked at closely. Only the outside of the top blade of a bypass lopper or pruner meant to cut delicate green branches, such as those seen on roses, will be sharp.
To re-sharpen the blade, use a sharpening stone or a carbide blade sharpener. Sharpen the bevel at the same angle as the initial slant with the sharpener. This ensures that while trimming branches, the newly sharpened blade cuts smoothly.
STEP 3: Stroke from the pivot to the blade’s tip.
When learning how to sharpen garden shears, pruners, and loppers, beginners’ largest error is to stroke the blades with the sharpener in a back and forth motion. This might result in nicks and a rough edge. The optimum way is to stroke the blade in one continuous motion from the pivot (where the blades unite) to the tip.
After a few strokes, thoroughly inspect the blade for sharpness. Depending on how dull the blade was, to begin with, restoring a sharp edge might take anywhere from 5 to 20 strokes.
STEP 4: Sharpen the anvil lopper blade on both sides.
Unlike bypass loppers, which have a sharp upper blade on only one side, anvil loppers have a sharp upper blade on both sides. Anvil loppers are designed to cut through hard, dead wood, and the double-sided blade is utilized to crush rather than slice the branch.
When sharpening an anvil lopper, perform the identical pivot-to-tip strokes on both sides of the blade, at the same angle as the original bevel.
STEP 5: Lastly, lubricate for protection.
Before storing garden loppers and shears, apply a little amount of oil on the blade and pivot region to help repel moisture and rust. Spread the lubricant evenly with a soft shop cloth and then wipe away any excess. This fast and easy process will safeguard the newly sharpened blade while still allowing the instrument to move freely.
I hope you got to understand how to sharpen garden pruner blades and do pruning smoothly.
