Looking at the butt end of the knife, where tip of blade is when closed. The blade is sandwiched by two steel liners, this is what you see on an older production Ranger.
Now take a look at a newer production Ranger.
Oooo, what's that, two hex cut out on the steel liners?
Reminds of you of anything? Yes? No?
How about that new Mike Horn Ranger where you can put a hex bit in handle?
The underlying structure is there, all you need to do it cut a hole (preferably not too ugly looking) on the plastic scale and you have another feature on your Ranger!
