An underwater weed cutter comprises a generally W-shaped object which is cut out of a plate or sheet of metal and is configured similar to two scythes whose opposite ends are joined together to form a unitary object which has a line attached to it to provide for pulling it along the bottom of a body of water to shear off and collect underwater weeds. The weed cutters are configured such that the outside or convex boundary of one of them is complementary in shape to the inside or concave boundary of another of them so that there is no metal waste developed between the cutters when they are being cut from the plate.
