I had a set similar to those but the "bits" were so long and thin that they were fragile and were lost and broken easily. I have a mini screwdriver that I can't find another on like. Its like those normal 4 way where it has two double ended bits and the shaft removes from the handle but its smaller than the rest of those, its only 4-5" long instead of the normal 10-12" long. The bits are slightly shorter than normal ones but are still the standard 1/4" hex. I'd like to find another one someday just for bob purposes (i'v learned not to decicate anything to a bob unless I have a way to get a spare or replacement for loss)
