A company called Sorako makes these precision screwdriver sets. The aim was apparently to cram as many tools as possible into the tightest possible footprint.Going over the company's materials, I was interested to see how the design of the bit holders evolved. In an earlier iteration of this set, the bit holders were deployed like this:Fairly clumsy. In the next iteration, they added a spring-loaded button mechanism:An improvement over the previous iteration, but a bit inelegant, and seems like the kind of thing that would break.For the latest version, they've gone with a push-to-open approach:The last one seems the best of the three, but I have a remaining UX gripe with the design:The graphics that show you which bit is which, are printed on the face of the bit holders. Once you deploy them, they lean forward and obscure the graphics, particularly if you've got this at desk level. Oughtn't the graphics be printed behind the bits, and perpendicular to the user's eyeline? What say you?
