A cutting blade (100) adapted to be carried by a tool holder (20) provided in a robotic work tool (10), the cutting blade (100) comprising a blade body (110) and a cutting edge (120, 121) extending along at least a portion of the periphery (111) of the blade body (110), and a slit (113) arranged to receive a pin (30) for attaching the cutting blade (100) to said tool holder (20), wherein the cutting blade (100) is movable such that the pin (30) may be displaced within the slit (113). The hardness of the cutting blade (100) decreases in direction from the cutting edge (120, 121) towards the center (125) of the blade body (110) such that the hardness of the cutting edge (120, 121) is higher than the hardness of at least a center portion (126) of the blade body (110). The present disclosure also relates to a method for manufacturing a cutting blade.
