This is the third pen pry I have purchased, and I have to say that the 6” is the way to go! The extra length gives you more leverage and reach. Its thin design makes the pen pry light, but do not be fooled. They are extremely tough. I would not hesitate to use mine on the most daunting task. It is too long to carry in my dress shirt pocket as a pen, which I still do with the regular length pen pry. But that is the ONLY drawback, and it still sits in my jeans or slacks pocket comfortably. The clip is just as stout as the prybar, so no need to worry about losing track of your tool. Amazing product. Amazing craftsman. Everyone needs two.
