Pole saw 6.3m (21′) Review [Updated 2020]. A pole saw is a saw attached to the end of a pole that helps with trimming and pruning the branches of tall trees.

It is an essential gardening tool in the sense that it makes trimming trees much easier and safer too.

So, if you are interested in getting one yourself, then I’d like to draw your attention to the HAYAUCHI 3-Ext. Polesaw 6.3m (21′). This is a great pole saw to own and, in this review, I will be discussing in-depth why that is.

A Brief Overview

The HAYAUCHI 3-Ext. Pole Saw is an excellent telescopic pole saw that is great for professionals and enthusiasts. As-built with aluminum, I have found this pole saw to be rigid and sturdy. The blade is oval-shaped. It is purposefully designed in such a way for better cut control during trimming or pruning.

The pole saw can reach up to a maximum of 21 feet. That is more than enough for most trimming needs. It can be shrunk down to 8 feet in length for better portability. The extensions are locked in by friction clamps that ensure strong and stable pole extension.

About the most important part which is the blade. The blade is a 390mm curved blade with a ratio of 6.6 teeth every 30mm. This high tooth density allows greater ease and efficiency during cutting. The company brags about their Silky 4 Retsume technology that promises great cut efficiency. And the real-life results are really not from it.

Besides the main blade the SILKY HAYAUCHI 3-Ext. Pole Saw has an upper sickle and a lower sickle. The upper sickle helps in clearing out vines and the lower sickle helps with removing epicormic and undercutting bark without damaging the tree. They also help with anchoring the saw during cutting and avoid slipping.

When it comes to using tools like these, safety should be your number priority. And the SILKY HAYAUCHI 3-Ext. Pole Saw does not fall behind in this aspect. The blade comes with a black rigid guard for user protection. The pole includes a shock absorber to protect the pole while resting on the ground.

Silky saws also provide replacement parts that you can buy for replacement. This is great in case your pole saw needs repairs in the future. Also, the toolless design allows you to easily replace any damaged part. You can easily re-sharpen the blade using a feather edged file.

The manufacturers also provide a lifetime warranty against defects in materials and workmanship.

How To Use A Non-Electric Pole Saw?

Step 1: Clear the work area

Before you start trimming you should clear out your working area. Remove any trip hazards that may be on the ground such as toys or gardening tools. Memorize where the tree roots are protruding out of the ground as you might trip on them. Make sure there are no people or animals within 50 feet around you while you work.

Step 2: Position the blade

First, extend your pole saw to its full length. Next, Hold the blade up high and then rest the weight of the blade on the branch you want to cut. Make sure you hold the handle at chest level and as close to you as possible.

Step 3: Position yourself

Don’t stand right below the branch you are about to cut. Stand at an angle to it. This will prevent the branch from falling on you and also help you in applying greater force for easy cutting.

Step 4: Apply the first stroke

The first stroke should be controlled and precise as it will guide the cut. So be mindful during the first cut. Focus on applying as much force as you can to form a deep groove for guiding your cut.

Step5: Continue cutting

After the groove has been made you can start speeding up your cutting motion. Guided by the initial groove, cut in an aggressive back and forth motion until the blade goes through the thickness of the branch. Stop as soon as the branch falls off.

Step 6: Clean up

After, you have completed trimming or pruning your tree begin cleaning the area. Then clean your pole saw and store it in a cool and dry place.
