摘要:
A cutting blade for a hand-guided trimmer with a drive motor has a disk-shaped base member with cutting teeth disposed about a circumference of the base member. The base member has a first face and a second face opposite the first face. The cutting teeth each have a tooth face edge, the tooth face edge leading in driving direction of the cutting blade and extending radially, and a tooth back edge extending in the circumferential direction. The tooth face edge and the tooth back edge of the cutting teeth are alternatingly ground on the first face or the second face in the circumferential direction and define together a common cutting tip that is leading in the drive direction. Several of the cutting tips of the cutting teeth that are sequentially arranged in the circumferential direction are positioned in a common plane.
