An extendable pole saw is a must for anyone considering pruning parts of shrubs and trees that are out of their reach. This device will enable the person doing the cutting to be stable while carrying out the task, with their feet firmly on the ground. There is no need to make use of a ladder and feel unstable.
This device consists of three important parts: the blade, an arm that can be lengthened and a handle. There is scope for designing many variations of this hand tool. The engineers have attempted to design an article that is easy to use and thus popular with consumers. They have produced different styles, to appeal to people\’s differing individual tastes.
When severing a branch from a tree\’s framework, the laborer should be able to grasp their equipment well. It is essential that the handle is easy to hold firmly, for reasonable periods of time. As it is used outdoors, the grip should also be made of a material that does not become slippery when wet.
In all probability the best feature of this equipment is its adjustable arm. A person can lengthen it up to 12\’ or shorten it to find the right position to enable the branch to be easily removed. It is useful to be able to retract it later when it is ready to be stored indoors in a small space.
The long arm can be made from aluminum or fiber glass. When fully extended, a quality device will not bend or jump out of the incision when the gardener is attempting to separate the offending limb from the tree. There should be a compromise between the lightweight material used for the telescopic extension and its ability to remain rigid while in use high amongst the branches.
Another aspect that is important in such a tool is the way in which the arm is kept fixed in position at the desired length. There are two common ways that this is accomplished. The one method is to twist the two extensions, which tightens them in place, keeping them from retracting when the forces involved in sawing are acting. The other method is to use a short lever clamp to immobilize them while doing the cutting.
Finally, the blade in an extendable pole saw will determine whether the equipment is of good quality. It will need to handle cross, rip or slant cuts when taking off branches. The cutting surfaces are curved for easier sawing and the teeth are specially designed to cut through the wood with only a minimum force being applied.
