If I use the Bison Design belt buckle at all in its tool mode, I expect to have my Wave in use along with it. That means I will have the bit extender - an absolutely marvelous gadget -, the bit kit array, a 4" adjustable wrench, and a small diamond file - all of which fit in the nylon Wave belt holster.

I regard the BD buckle as an extra, "no cost" appendage to this admittedly sparse tool kit. It is no cost since I will have a belt with buckle anyway, and it might as well have an additional use. I wouldn't be surprised if I didn't have to separate the buckle from the belt (easily done) to actually use it.

I find the bit extender really useful - often I can use it with an appropriate bit, and never use the Wave at all. Even better is the bit holder, with or without the extender, on the skeletool - it is becoming my 'go to"screwdriver for odd jobs, even in preference to a conventional tool.
