A screwdriver is the single most essential tool for minor home repairs. It’s the ultimate kitchen-drawer tool, and it can help with loose hinges, toy batteries, and wobbly door handles, all on the fly.

To get the most out of a screwdriver, you need one with a good bit selection. Other pluses include a comfortable-to-hold handle and nice ratcheting action. In 12 years of researching and testing screwdrivers, we’ve found that the Megapro 13-in-1 Multi-Bit Ratcheting Screwdriver is the one tool that gets everything right.

This manual screwdriver combines smooth ratcheting action with excellent bit storage and a uniquely comfortable handle to be the most well-rounded, capable tool of its kind.

Nearly identical to our main pick, this automotive version takes universal 1-inch bits. But it typically costs a little more, and the bit selection isn’t as good.

If the Megapro and Channellock 13-in-1 models are not available, we recommend the Ratcheting Automotive Screwdriver. In almost all ways, it’s identical to our pick, as it has the same handle, the same nice ratchet, and the same style of storage system. The difference is that it takes smaller, single-sided 1-inch bits, rather than the double-sided bits that our pick takes. It’s nice that these bits are more easily replaceable, but the initial selection that comes with the screwdriver isn’t as useful. This model is usually about $10 more expensive, too.

This model is a lot like our main pick, but it’s not as comfortable to hold, and the ratchet toggle is more difficult to use.

Tinier screws and delicate projects require a smaller tool, and for that we recommend the 24-in-1 Multi-Bit Precision Screwdriver. In many ways, this is the little sibling to our main pick, as it has the same smart bit storage and the spinning cap. The bit selection is also impressive, but it represents the smaller spectrum of sizes, including Apple’s pentalobe bit. It offers a teardrop handle similar to that of our main pick, as well as the comfort that goes with that shape. The rear cap spins much more freely, making delicate work easier. It doesn’t have a ratchet, but given the size of the screws it handles, we don’t think this is an issue. Among all the other precision screwdrivers we tested, none offer as much as the 24-in-1 in a single, compact, easy-to-use package. The only significant downside of this model is that it has trouble with recessed screws because of the way the replaceable bits fit into the stem. But for a general-use kitchen-drawer tool, this screwdriver makes a nice companion piece to the larger 13-in-1. We have more thoughts in our guide to precision screwdrivers.
