Bit driver feature with potential for further uses of same

Hi all,

Anyone ever caught themselves asking either or both of the following questions?
1. Why doesn't the bit driver allow bits (or extender, for that matter) to stay inside also under traction? Would be useful for a corkscrew, for instance, or any other tool that is loaded under traction... such as a saw blade...
2. What is the strange squarish transversal hole in the bit driver for anyway?

I have, but so far without connecting these points. Guess it's a sign of growing old...  :think:

Have a look at the patent covering amongst others the bit driver, first introduced with the Charge: https://patents.google.com/patent/US7347128 - a look at Figs. 13A-F is instructive. Apparently this was considered...

To my knowledge LM never marketed any kind of tools or accessories of this kind - correct me if I'm wrong, anyone?
Have any of the modders ever tried to use this feature somehow?

BTW, the patent also covers the Kick and the Removable Bit Driver in some detail.
Cheers!

Technically, they have... see Fig 14-16 :D, although it is a bit of a stretch to call the clip a tool.

Effectively, you could design any tool to fit that hole (Several people have produced saw blades that fit).

But I would like the idea of a locking bit-holder, similar to those already available for powertools.
It wouldn't be the internet without people complaining.

From the patent:

Quote
An access opening extends transversely through the body from one to the other of the opposite sides, at a location spaced apart from the outer end by a distance of, for example, 0.47 inch. As a result, an end of a tool bit opposite the driving end in use can be seen while the bit is held in the tool bit holder. The access opening also permits any dust or other foreign material that has entered into the bit-receiving cavity to be dislodged or to fall free from the body.

It probably gives a more precise depth stop for the bits, and it could also be a feature that allows for the manufacturing tooling (this part looks like it's die cast) to be more reliable.  The end of core that forms the orifice the driver bit goes into can locate into another part of the mould tool, rather than only being supported at one end.
