CarbideCruzer:
This is an interesting coincidence. I was, in the last few days, trying to find out more about the kit. I bought it last spring and it included the pouch, bits and adapter. They had been wet so all the tools were rusty and the pouch was stained. I cleaned them up and noticed that the pouch said "made in U.S.A." Maybe this is old stock - I have no idea. The pouch, although still usable has seen better days and the plating has come off the bits and adaptor. They still work well however.
The adaptor fits on the Phillips of the multiplier, mp400 and mp600 for sure and also fits properly on the (almost) square post of the Ganzo G301. The Ganzo was missing the adaptor and bits that it comes with so I ordered a set from aliexpress a few days ago. The one's on aliexpress come in a rubber holder, not in the nylon pouch. I'm hoping (assuming) that the adaptor in that set will also fit the Gerber multitools.
Yesterday I located an adaptor that also fits the Gerbers and Ganzo, in a second hand store. They adaptors are available separately on aliexpress but I can't seem to find them locally other than the one and it is unlabelled.
