An adjustable hinged corner trowel is formed from hinged plates with a
removeably attached handle. Cooperating control arms connect the handle
to the hinged plates. The control arms are fixed to the hinged plates and
can be fixed relative to each other at the handle by cooperating teeth
and grooves. The handle has a threaded member capable of receiving a wing
nut to fix the control arms against each other. Thereby, the angle of the
hinged plates may be adjusted. The hinged corner trowel establishes both
sides of any angled corner at the same time for utilization on drywall or
similar materials.
