Secateurs

Bypass secateurs: cutting of branches on live trees / bushes
Bypass secateurs and delimbers are used for cutting of branches on live plants therefore cutting consequences for a plant have to bytminimalny.
The bypass cutting head (Bypass) was called so because the cutting knife as if passes by (pass by) of a counteredge. Bypass edges of Bahco in the course of cutting smoothly crash into a tree. Such technology demands smaller efforts, and keeps branches due to reduction of pressure better.

Basic secateurs: cutting of thick and dry branches
Basic secateurs and delimbers are used in cases when the main task – to remove a branch, and
purity of a cut is of secondary importance. The cutting edges in this case narrower and sharp in comparison with bypass. At a scrap of thick and dry branches the knife puts the bigger pressure upon a tree.
The basis (support) supports a branch, and distributes pressure, reducing a plant damage rate.
