This video is a demonstration of the total inconsistency and inaccuracy of a nail-in-the-wall as a method of balancing a rotary part such as a lawnmower blade. The only industry accepted method of balancing lawnmower blades is with a professional static balancing instrument manufactured by Magna-Matic. In 1958 Magna-Matic invented the lawnmower blade balancer, and it remains the industry standard used by lawnmower blade manufacturers, lawnmower dealerships and lawn care professionals.
