Reddit mentions of Wera 05051274001 Bit Holder 813 1/4x78mm

Nah, not going to find that in one kit unless you get Wiha's 50 piece master set.

What I've found is that buying drivers individually is often not much more expensive than buying sets, and may be cheaper if it avoids buying unneeded or duplicate drivers.

I myself have the basic drivers (PH, slotted, t10+ torx) wera and felo drivers, and use 3" bits for the more obscure stuff. I particularly like using this wera bit holding handle with 3" bits. Handles like a regular small screwdriver.

I usually buy my individual drivers from KCToolco, their search tools makes it easy to find all the different sizes you need. You can usually find them a bit cheaper on Amazon if you find all the part numbers elsewhere.

I bought this set of phillips bits, and have found them extremely useful for electronics work. Many modern electronics are assembled with screws that have PH2 heads, but are too narrow for a normal PH2 driver to fit. The set of bits I linked above includes some that are basically PH2 size but narrowed down. Really makes a big difference on preventing stripped heads.

I do like the sound of adding some more Vessel tools to the kit. I think I have a mild screwdriver addiction at the moment. lol. Half the hex bits in the kit are actually Vessel bits.

I'm actually thinking of adding something like the Wera mini bit screwdriver, with some long reaching bits that could hopefully take the place of the Klein on the side.

The Klein works great, but I'm trying as best I can to make things as functional as possible, without having extra tools in there.

These things are tiny, but not a bad size really. I ordered what I thought was one of the Wera bit holder and got three which is fine by me. Also got a set of Wiha T5-T10 Torx bits to go with it.

Haven't really used them yet but they seem nice.
