ABSTRACT:
A hand finishing tool for dry wall board installation consisting of three operative components: a main body comprising a planar sheet material formed into two substantially flat sides extending radially from the common line to define a dihedral configuration; a manual tool gripping means pinned at its stem end to the inner surface of the main body; and a tool biasing means adapted, upon digital manipulation, to outwardly bias the flat sides to temporarily enlarge the angle that the sides normally define during tool use.
