PROBLEM TO BE SOLVED: To produce a hoe having a blade body equipped with side blades as well as fork parts, as strong, with ease. SOLUTION: This hoe is constituted by a long shaft and a blade body 2 attached at the tip end of the long shaft. The blade body 2 is provided by installing a multiple number of comb plate parts 21 as protruded at the front edge side of a plate-formed base plate part 20 and also being equipped with fork parts 23 formed by twisting the comb plate parts so as to approximately cross at right angle with the base plate part, cutting blade parts (horizontal blade parts) 25 formed at the front edge of the base plate part between the fork parts and a shaft-mounting part 26 installed at the base plate part, forming blades (vertical blade parts) 24 at the upper surface side of the blade body facing toward the long shaft side in the tip end and tip part of the fork part 23 and making the cutting blade parts (horizontal blade parts) as recessed and curved blades.
