Abstract
A mixing tool for installation in a mixing container and method of making same. The mixing tool has a disc-shaped member with a semi-circular section connected in radially spaced relationship to a rotatable shaft so as to be coaxial therewith and has plane top and bottom surfaces perpendicular to the axis of rotation of the rotatable shaft. The disc-shaped member also has a twisted section merging with each other the top and bottom surfaces of the semi-circular section and likewise arranged and connected to the shaft in spaced relationship thereto. The mixing tool is preferably made from a circular disc with plane top and bottom surfaces, which is cut open by a single radial cut. One of the cut end portions is then twisted and reunited to the other cut end portions whereupon the thus obtained member is arranged in spaced relationship to a rotatable shaft and connected thereto.
