The most powerful of hoes are the push hoes. They have a distinctive design wherein their shank is split and fastened at each end of the blade, rather than the middle. The shank arises from a socket which surrounds the end of the handle. The blade is slightly thicker than other weeding hoes. The tools are designed for heavy-duty weeding and can keep sharp when wielded properly, make short work of thistle, dock and even--in my experience--sprouting Washingtonia Palms.
