I got this for one of my rolling tool bags for when I am running data lines and need to gut openings for drop boxes. It has a really sharp tip so can easily penetrate drywall with a couple of pounds to the end of the handle. I love that it folds away protecting the blade when not in use and your hands and other tools from what is a durable and sharp blade. I love that it can also be used on backerboard and PVC, although I have not tried it out on those as of yet.
