• With this clever-ish set you can pick two drivers, mount them in the flip-housing, and then go back and forth between them quickly.

• There is a strong temptation to use the double-ended bit from a flippable screwdriver as a power driver bit if you can’t find a proper one. This results in your having a nut driver instead of a screwdriver when you inevitably fail to reunite the bit with its handle.

• This flip-type multi driver goes above and beyond by having an extra level of flip-able part at each end, giving you eight screwdrivers and two nut drivers!

• Multi-drivers that store bits in the handle seem like a fine idea, but they just annoy me for some reason. There’s no satisfaction is switching bits, not like the smooth, satisfying flip of the other kind.

• The basic six-function flip-able screwdriver has two slotted and two Philips bits, and two sizes of nut driver. The big issue is whether both slotted (large and small) are on one side and both Philips on the other, or both small sizes are on one side and both large sizes on the other. Because I have several of each kind, I never know whether to pull out the bit, or the main shaft, when I want to switch to the other kind and/or the other size.

• Storage Multi Driver

• Now here’s an oddball: an antique three-headed screwdriver with an entirely unique method of storing and deploying the bits.

• Going in the other direction, this stubby driver has only two ends.

• This star driver dispenses with switching bits entirely, and just has them all exposed at once. Which of course means it won’t work near any obstruction, or on screws even a little bit under the surface.

• These beautiful snowflake drivers go even further, combining screwdriver tips with several sizes of nut driver. Pretty useless unless the screw or nut is way out in the open just asking to get screwed.

• Star Driver Set

• This ratchet handle lets you decide if you want it straight, sideways, or somewhere in between.

• As soon as the handle veers off in the sideways direction, a ratchet becomes almost necessary. Otherwise the handle would have to be turned all the way around, and could only be used away from any obstructions.

• Straight ratchet drivers look just like normal screwdrivers, but if you turn the handle backwards it clicks and then you can go forwards again without repositioning your hand. A slide switch determines which way is forwards.

• Stubby flippable screwdriver.
