A corner mud applicator pan is provided. The corner mud applicator pan is especially suitable for use in applying beaded mud to corner units for drywall in construction of walls. The applicator pan has a V-shaped opening at the bottom of the pan which has insert guides (or “leads”) which makes insertion of the corner unit into the V-shaped opening easy and efficient. Support lines add strength to the pan and horizontal grip lines increase the grip for the user.

Provided is a tool that includes a handle assembly including a top portion and a bottom portion. The tool also includes a lock plate disposed between the top and bottom portions and having a deflectable arm having a free end biased towards the top portion, a fixed end opposite the free end, an inner edge, an outer edge, and a detent near the free end and the inner edge. The tool additionally includes a blade having first and second ends, an indent in a bottom surface of the blade near the first end for engaging the detent in a closed position, and a ramp on the bottom surface near the indent defining a reduced thickness portion of the blade that reduces in thickness from the indent towards an edge of the blade to reduce contact between the detent and the blade during rotation of the blade.
