Disclosed is a refiner filling piece for a refiner having a rotor that rotates about an axis of rotation and cooperates with a stator to mechanically treat a pulp containing cellulosic fibers. The refiner filling piece is mountable to the rotor or the stator. The refiner filling piece comprises a base and a plurality of spaced-apart refiner bars, each refiner bar being defined by a bar length and a bar height. At least some of the refiner bars have a surface coated with a variable coating. The surface having the variable coating may be the leading surface of the bar.

A blade element pair (20) for a refiner (1, 2, 3) is intended for refining fibrous material. Each blade element (5, 5, 8, 8) of the blade element pair (20) has a refining surface (6, 9) with blade bars (16, 18) and blade grooves (17, 19) extending along the blade element (5, 5, 8, 8), and openings (14,15) extending through the blade element (5, 5, 8, 8). The openings (14, 15) in one of the blade elements (5, 5, 8, 8) is at different axial (A) or radial (R) positions from the openings (14,15) in the other blade element (5, 5, 8, 8) when the blade elements (5, 5, 8, 8) of the blade element pair (20) are set substantially opposite to each other.
