  • Patent number: 6564881
    Abstract: A mixing hoe including an elongated handle and a hoe blade attached to the handle is adapted for mixing material in a walled container. The blade forms a bottom edge, opposing upper edge, and first and second opposing side edges. The upper edge has adjacent edge sections extending outwardly and downwardly, from a central recess or opening in the blade upper edge, to respective first and second side edges. The upper edges are bent backward for creating flow patterns. The first and second side edges extend downwardly and inwardly from the upper edge sections outer extremes to the bottom edge. The edges are sloped and the edge corners are rounded to closely resemble container corner and wall characteristics. The blade is manipulated by a user grasping the handle to position at least one of the five scraping edges (two top, two side and bottom) against the base and walls of the container to scrape away material adhering to the base and walls of the container during mixing.
