Claim 8:
9. Deflaker plates for a deflaker machine, the deflaker plates comprising:
a first deflaker plate comprising:
a first substrate including a surface; and
a first plurality of teeth extending from the surface of the first substrate,
wherein a first specified number of teeth of the first plurality of teeth each comprises a serrated face,
wherein serrations on the serrated face have peaks and valleys,
wherein each of the peaks and valleys are directed across the serrated face in a direction of rotation of the first deflaker plate, and
wherein each of the peaks and valleys are oriented to either be parallel with the surface of the first substrate or define an acute angle relative to the surface of the first substrate; and

a second deflaker plate comprising:
a second substrate including a surface; and
a second plurality of teeth extending from the surface of the second substrate,
wherein a second specified number of teeth of the second plurality of teeth each comprises a serrated face,
wherein serrations on the serrated face have peaks and valleys,
wherein each of the peaks and valleys are directed across the serrated face in the direction of rotation of the first deflaker plate;
wherein each of the peaks and valleys are oriented to either be parallel with the surface of the second substrate or define an acute angle relative to the surface of the second substrate, and
wherein the first plurality of teeth is configured to intermesh with the second plurality of teeth.
