Abstract
A cutting blade assembly incorporating two lawnmower cutting blades and a holder configured to hold the lawnmower cutting blades in perpendicular orientation with respect to each other. The holder does not occupy any space on the lawnmower blade mounting shaft and results in less rotational inertia than conventional mounting hub designs.
