If you actually use your Kershaw 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.You might want to remove the pocket clip or change its placement. (Many Kershaw knives enable you to switch the pocket clip for tip-up or tip-down carry. Some let you switch the clip for left- and right-handed use.) If you want to do any of those things, the quickest and easiest way to do so is to take out your handy T-Tool and make the adjustment.The T-Tool comes with T-6, T-8, and T-10 bits-and those will take care of any Kershaw or Zero Tolerance knife. The bits store in the aluminum shaft of the tool and the head is magnetized to make it easier to change bits. To make it super-easy to always have the tools you need, the T-Tool comes with a removable key chain ring. Carry it with you and if you need to make an adjustment, you"re always prepared.
