This is a good little tool to have. It is a little 4 inch ratcheting screwdriver. It is reversible, and also has a stop mechanism to use it like a regular screwdriver if you wanted too. It comes with 4 bits. It uses standard sized bits for it. This has a comfortable ergonomic handle. This will ship fast and safely. If you have any questions send me a message.
