Patent attributes
A locking tool includes a handle and an elongated tool blade having a body and a tang. The tool blade has a tang spline opening formed therein which defines an annular array of alternate spline teeth and splined slots. A transversely-extending lock member has a spline ring with an annular array of alternate spline ribs and spline grooves formed thereon complementary to the tang spline opening, and is translatable between a locked position and a released position. The tool blade is attached to the handle by the locking member such that when the lock member is in the released position, the tool blade is freely pivotable about the locking member. When the lock member is in the locked position, the spline ring engages the tang spline opening such that the tool blade is retained in one of a plurality of predetermined angular positions relative to the handle.
