Charles Noble and the Noble Blade

Charles Sherwood Noble, farmer, inventor and entrepreneur, showed the farming potential of the drought-prone Palliser Triangle. During the Great Depression he worked with the Dominion Experimental Farm to promote dry-land farming methods, and in 1936 invented the Noble Blade, a cultivator that cut weeds at the roots without disturbing the soil, greatly reducing erosion. His company became Alberta’s largest maker of such implements.
