This is my patent pending idea of a hairbrush consists of twisted brushes.
I use a grinder, an impact drill, a vise, and a screw to make them without jigs. Very easy and simple! I do the same method of making "DIY Handmade Hairbrush 1 & 2".
Things will be needed are a wire and bristles. I use an impact drill to make twisted brushes. It requires knowledge and skills how to set the bristles on the wire and then twist the wire. They are finished by cutting the wire and bristles short. I learned to refine wild boar bristles on my own.
