Multicraft seems like a Swissgrip with CAB and a textured surface.
Better is subjective but you can't just claim they're better. The only difference with the tips is that the Vessel doesn't have any tips with an oxide coating but they are magnetic. PB Swiss has the oxide coating but they aren't magnetic. Vessel says it's cellulose acetate resin but doesn't specify if it's CAB or cellulose acetate. I wouldn't claim the PB Swiss is better as you're comparing Swiss to Japanese steel. I'd like to know where from where you claim that the blade steel is better, tips are better, plating is tougher. That's quite the assumption to make since Vessel makes some of the best screwdrivers in a market full of competitors from Europe, Asia, America, and elsewhere. If you can provide reliable sources or links to a comparison of PB Swiss classic/multi-craft directly to the Vessel Crystaline series I'll look at it. Maybe I'll even ask to borrow classic/multicraft from a few people I know for direct comparison. I also covered the cost of the individual screwdriver here:
With regard to the Multicraft, essentially yes, although it’s actually the other way round as the multicraft predated the Swissgrip.
I believe the PB Swiss to be better, based on 25-30 years of using PB Swiss, some of it in an industrial environment, and probably even longer of using Vessel, which has been a common name in the U.K. since the early 70’s at least.
I say that the steel and tips are better on the PB than the Vessel because I have encountered several Vessel slotted drivers with distorted tips over the years. Not so the PB. I’m not saying the Vessel are failures, they are very decent tools for the price, but the steel on the PB holds up better.
I say the plating is better on the PB because I have encountered Vessel drivers with stripped plating, but again I have yet to do so on the PB Swiss, and I have some that have had very hard use.
Vessel say their handles are cellulose acetate. If it was CAB I’m sure they would say so, and it looks, feels, performs and smells like cellulose acetate to me.
I don’t have any problem with cellulose acetate handles whatsoever, and I’ve never seen a broken one (Scuffed maybe, broken no) but I can’t deny that the CAB is more impact resistant, so I’ll go with ‘better’.
