I was using with my handy Charge TTi and thought about liking to simply carry the bit extender without the sheath, in my pocket.
Came up with this.
How about adding to the existing metal removable pocket clip two wings on either side of the stamping, that are then folded into a clip, similar to a flashlight holder. On the outside of the clip.
This would let you push the bit extender onto it and would simply hang on the outside of your pocket. Nicely and snug against the existing lip and the knurling on the bit extender, without slipping down or up.
Here is a quick sketch if I can add an attachment.
Might try to mock one up if I can get some spring steel.
Oh long time fan/lurker, first time poster. Really great site!
