....Alright,if you need an example of dedicated excess...here is my "handy" Wiha driver roll. The picture shows them to be similar,but the third roll in the fore-ground,is System 4,4mm,and the other two System 6.
It has 000 to 3,pozi,philips,torx,allen,ball,etc,and adjustable length blades.
It was a lump of brass,to assemble,and don't try to buy the triple roll - you can't - we made it out of three,on an 1890's Singer,which can sew leather
It was made as an carry set,and fits in a large,side pocket,then unrolls and hangs,either way,from a hook or magnet. If i had a pound,every time someone sees it unrolled,and says "Blimey!...that's cool....where did you get that?..." i could build another!
It's the kind of set which you just have handy...and can stick anywhere....only i don't feel like doing that,coz it cost a fortune
