Grip-Switch v1 Guitar Knob

Here's a cool knob designed especially to be used with push-pull pots/knobs on electric guitars. I found the standard knob styles, with the widest part of the knob at the base, hard to grip when pulling the knob up to activate the switch. These knobs not only look great, but give you something to grab on to when switching positions on your push-pull potentiometer. These are designed to be a universal press-fit for knurled split-shaft potentiometers. They work equally well on coarse (18 spline, ex. Alpha) and fine (24 spline, ex. CTS) potentiometer shafts. I have also tested on the non-split knurled shaft PRS 5-way switch will fit, as shown in the pictures, although it is tight. So, what will it be - a tired old design made in China, or a functional and aesthetically grabbing knob designed and made in the USA?
