The length is very common and they are built to last. They are an excellent addition to a tool box and they don't take up much room either. I have used mine a long time as needed and have not had a problem so far.
The craftsman torx screwdriver has the classic craftsman hard handle which it will last a long time and the handle fits your hand well and the torx tip has held up well also.
Great craftsman product the can take abuse and still function the way it was intended.
