A drywall hopper assembly that contains a double blade that can apply drywall mud to both interior and exterior drywall corners with no blade change. A zig-zag blade can contain two parallel grooves, one for interior corners and one for exterior corners. With this blade arrangement, an operator can quickly move from one type of corner to another without using multiple tools, multiple blades or hand application methods to apply mud. The present invention can contain a pliable release port to present mud equally to an interior or an exterior corner. There can be such a port on both the top and bottom of the blade so that mud is smoothly applied as the operator moves the tool along the seam.
