Secateurs
A pruning shears , secateurs or pruning shears or, in forestry also Astungsschere called is particularly suitable for cutting thin branches and shoots. It is used in rose plants , grapevines , in fruit and horticulture and similar areas.
history
The first modern garden and rose shears are known from 1819. The French aristocrat Antoine-François Bertrand de Molleville is named as the inventor in the French gardener's handbook Bon Jardinier . The secateurs came to Germany around 1850 due to viticulture.
Cutting principle
There are two main cutting principles for secateurs: anvil and bypass. With the anvil cutting method, the blade hits a flat surface, similar to the principle of an anvil and hammer. The object is only cut by the striking blade. This can easily cause bruises on the branches. However, this method allows thicker branches to be cut with a little less effort. This is an advantage for pruning trees or for repetitive work.
Another principle is used in the bypass method. Here two blades run past each other and cut the branch from both sides. This results in fewer bruises and the branch remains uninjured.
Furnishing
Rose scissors have well-designed, hardened steel blades, sometimes with a non-stick coating, non-slip handles and a lock with which the self-opening scissors can be locked when closed. A notch for wire cutting is often found on the upper blade near the pivot point .
Further development
In addition to the normal pruning shears, there are also pneumatic and electrical versions that require less effort. Furthermore, cutting and handles are adapted for garden shears for left-handers .
