If you actually use your Kershaw pocket knife at all, at some point you're going to want to adjust it. You might want to tighten a screw that's come loose. You might want to tighten or loosen the blade pivot to suit your personal preferences or adjust a blade that’s loosened up over the years—or came too tight from the factory. With the Kershaw Torx Tool bit driver, you'll be able to adjust all of your knives and more!
