Claim 17:
18. A refining member for a pulp refiner, the refining member comprising:
a disc-shaped refining body including a planar refining surface comprising:
refiner bars projecting outwardly from the planar refining surface to a first height, each of the refiner bars extending from a radially inward position on the planar refining surface to a radially outward position on the planar refining surface; and
teeth projecting outwardly from the planar refining surface to a second height greater than the first height, the teeth being spaced apart from the radial outer edge of the refiner bars by a substantially planar area,

wherein the refiner bars are adapted to refine wood fibers and the teeth are adapted to break up fiber bundles.
