What is a "corner trowel"?
A corner trowel is a hand tool used in drywall and plastering work to smooth and finish the inside corners of walls. It has a blade shaped to fit the 90-degree angle of a corner, allowing for a clean, even application of joint compound or plaster. The tool is designed to create sharp, professional-looking corners without creating excess material buildup. Corner trowels are typically used for finishing drywall joints in interior corners, providing a smooth, seamless transition between two walls.
