Bypass scissors - this is how the mechanism works
The bypass scissors work with two sharp blades. Place a twig between the blades, slide them past each other and cut the plant tissue. The advantages and disadvantages of the bypass function are summarized in the following overview:

| Bypass scissors | advantages | disadvantage | suitable for |
|---|---|---|---|
| precise cut | higher effort when cutting | soft, thin wood | |
| no crushing of the tissue | rapid fatigue of the wrist | Roses, Cuttings, green waste |
The precise, clean cut of bypass scissors speaks primarily for use on shrubs and perennials with thin shoots up to a thickness of 2 to 2.5 centimeters. Since there are small and large scissors for left and right-handers with and without telescopic handles, we recommend trying out the favorite before buying it.
Anvil scissors - how they work in a nutshell
The anvil scissors only work with one sharp edge. This blade cuts the wood and hits a blunt counterpart, the anvil. Since hardly any transverse forces occur with this mode of operation, the anvil scissors score with better power transmission compared to the bypass scissors. The advantages and disadvantages of the anvil mechanism can be found here:
| Anvil scissors | advantages | disadvantage | suitable for |
|---|---|---|---|
| no tilting | Risk of bruises on the drive | dry and hard wood | |
| little effort | less precise cutting | Thinning out dead wood | |
| less wrist fatigue | frayed wound edges on the soft wood |
The better power transmission of anvil shears speaks for their use on branches with a thickness of 2.5 to 3.5 centimeters. Technical refinements minimize the effort required to guide the cut, such as long scissor arms, a built-in gear or a stepped ratchet mechanism.
Tips
The specific advantages of the bypass and anvil mechanism only come into play in the long term if you use the scissors regularly maintain and sharpen. Carefully clean your garden shears and loppers from dirt after each use. At least once a season you should use the blades with a whetstone sharpento always leave smooth cuts on your trees.
