This Kobalt screwdriver set may cost a few extra dollars but we believe you really get what you pay for when it comes to tools. This solid tool has a double-drive design that has been fully patented. This tool is said to give double the efficiency of a standard ratchet screwdriver which will make any projects you take on, faster and easier. The screwdriver features a special one handed locking system with a special ball bearing lock mechanism. The molded handle has been built for grip and comfort and the bits have been manufactured for longevity. The screwdriver set comes with 34 bits but we were quite disappointed that there wasn’t a carry case included.
