This design has developed over the centuries as an exceptionally efficient working tool for the Japanese gardener and farmer. The inward curve of the sharp pointed blade coupled with the deliberately acute angle of the blade and the short 13'' long wood handle means that as you swing the handle the natural movement of your arm pulls the blade toward your body as it enters the soil - an example of logical ergonomic design centuries old. This tool is a natural winner for anyone who works close to the ground. Highly recommended.
