The different types of pruning shears
Pruning shears differ from each other mainly in the type of blades and in their operating mode. As for the first aspect, that is the length of the blades, this characteristic mainly depends on the plant that must be pruned. In this regard, therefore, there are the bypasses (characterized by curved blades, which allow a very precise and clean cut); the anvil ones, with straight blades, to cut dead branches not very thick; the ratchet ones, with extendable handles, to cut the thickest and hardest branches. The latter are also known as loppers. As regards, however, the operating mode, there are those with manual cutting, the electric ones or the pneumatic ones. The last two types are purely recommended for professional use.
Characteristics of pruning shears
The blades are generally made of steel, sometimes they are also covered with a special non-stick material: this means that liquid substances (such as tree sap) can easily slide off. Other models, however, are made of carbon, a material that makes them much more resistant and easy to handle. The handle of the scissors is also important: it must be ergonomic, that is, with a shape that guarantees the correct manual grip. Often, there is an outer coating of non-slip rubbery plastic. Generally, moreover, all types of scissors on the market are equipped with a safety mechanism, which allows you to lock or unlock the closed position, avoiding accidental cutting. Finally, the blades must be periodically sharpened, to obtain good clean cuts.
