The Berger gardener's saw 61510 , with replaceable high-performance saw blade , made of corrosion-protected carbon steel , has triple-ground and impulse-hardened tooth tips . This guarantees a long service life for the coarse-toothed saw blade (7.5 teeth per 3 cm), which only works when pulled and ensures a straight and clean cut, as well as the removal of the resulting chips in soft wood. This reduces the surface area of ​​the cuttings that is vulnerable to bacterial and fungal attack. The sheath protects against injuries during transport and handling and thus offers ideal protection for people and the saw blade.
