Hi,
After years of use/abuse, my screwdrivers need replacing. Can anyone recommend any good ones to get or warn me of bad ones to avoid?
I see that there is this set by Wera

claims to reduce cam-out by having grooves in the tips. It seems screwfix also sell wera bits for electric screwdrivers: some with grooves and some with diamond particles in to help them grip.
Do any of these work or are they just gimmicks?
Are the handles comfortable to hold, they look a bit odd in the photo.
They also sell two sets with "shaped" shanks. This one is square:

this one is hexagonal:

claim it is so you can use a spanner to get extra torque. Has anyone ever used a spanner on a screwdriver to release a tight screw? It sounds like a good idea in theory but I wonder if it really works in practice or whether this is just another marketing claim?
TIA
