Looking at bit holding screwdrivers, what would you go for? I have one of all common bits in 89mm, and multiples of everything else in 25mm. Don't really want to go buying more in 50mm, although I do have impact ones.
8451 short (32mm shaft, 135mm overall) - short, but a little longer than my Wera 816 R and with shallow insertion depth, so perhaps just long enough to be practical with 25mm bits. Suits 89mm bits for length, although the short insertion depth and only a magnetic hold might not be ideal for that, and magnetism won't reach the tip to hold the screw. This is the one that caught my eye at first.
8451 long (100mm shaft, 205mm overall) - for 25mm bits only. Not too similar to things I have already. Strongest bit magnet available on a long driver without going for bulkier mechanical locking holders. Probably my current leading contender.
8215 handle & 215.M bit holder blade (60mm or 100mm shaft) - wildcard option, no real interest in the rest of the system but leaves the option open. Not much more money to get both shaft lengths, or say a PZ2.
Additionally looking at T-handle bit holders, for smallish quantities of tight things like wood self tappers that tire my hand out with a screwdriver but don't warrant getting a power tool out, or where sensitivity feeling is needed towards the end. 1254 (30mm or 100mm shaft), or 1255 MR ratcheting (80mm shaft). I wonder if non-ratcheting would be a pain to use especially being asymmetric. I've used 1/4" square ones with sockets before and you have to go in 180deg hand rotations, and reposition on the screw head if you want to get the handle in a better orientation when it gets tight. I don't mind symmetric P handle hex/torx drivers for bike work, but little torque needed except for final tightening and initial loosening.
I like the 6465 because of the bit storage. For my use, thats a benefit.
