Brush cutting blades that are attachable to a brush cutting device to drive rotation of the blade are shown and described. Each of the blades includes a planar main body, upwardly projected teeth upwardly disposed relative to the planar main body, and downwardly projected teeth downwardly disposed relative to the planar main body. The upwardly and downwardly disposed teeth are disposed on a periphery of the planar main body. In some examples, the blade includes planar teeth aligned with the planar body. In some further examples, planar teeth are alternatingly disposed between the one or more upwardly projected teeth and the one or more downwardly projected teeth.
