The base cutting blade includes a first cutting edge formed on one edge, extending inward from a first end thereof and a second cutting edge formed on an opposing edge, extending inward from a second end thereof. A middle section of the base cutting blade may have any suitable hole (s) or opening pattern (s) to accommodate attachment to a drive shaft of a lawn mower. The at least one mulching cutting blade may be a single mulching cutting blade, which is bolted to the drive shaft, or two separate mulching cutting blades, which are attached to the base cutting blade with any suitable method, such as welding. A first mulching cutting blade includes a first mulching cutting edge and a second mulching cutting blade includes a second mulching cutting edge.
