Modifying a Paint Brush by Melting Bristles for Angled Edges

What happens here

This step demonstrates an unconventional and generally not recommended method for attempting to create an angled sash brush from a straight, flat paint brush. A utility knife, which appears to be heated, is used to cut and melt the bristles of the brush at an acute angle. The process involves pressing the hot blade into the brush bristles, causing them to char, melt, and sever. This action reshapes the brush head into an angled profile, ostensibly to facilitate 'cutting in' or painting clean lines along edges and corners. The video later shows a brush with an angled profile being used to apply orange paint along a wall corner, illustrating the intended application.

Goal: Reshape a straight paint brush into an angled sash brush for precise edge painting.
