Abstract: A blade element (11) for a refiner (10) for refining fibrous material has a blade element body (12) and blade bars (13, 13a, 13b) and blade grooves (14, 14a, 14b) therebetween. Bottoms of the blade grooves (14, 14a, 14b) have, in the longitudinal direction (LD) of the blade grooves, a variable depth profile comprising alternating high points (14a′, 14b′) and low points (14a″, 14b″) so that there is a phase shift (X2) between the high points (14a′, 14b′) and the low points (14a″, 14b″) of the variable depth profiles of the bottoms of the adjacent blade grooves (14a, 14b). Also, a refiner (10) for refining fibrous material and a method for manufacturing the blade element (11) for the refiner (1).
