What is knurling and where is it on a guitar?
Knurling can be found on your volume and tone knobs. This helps you grip and turn the knobs better especially as you hands sweat after much playing. Knurling can be horizontal like on your Stratocaster knobs or have diamond shaped serrations on the circumference of the work providing a better gripping surface. A good example of diamond shaped serrations is on the dome Fender Knobs used on Telecasters and early Fender lap steels. The knurling comes in three basic diamond knurl patterns, course, medium and fine pitch. The knurling tool mounts to a lathe tool post. The knurl pattern is raised by rolling the knurls against the metal to raise the surface.
