We have a saying that the best knife is the one that you have with you! Always be prepared with the new Key knife. This is the first lock-back of its kind. Open up your awareness. We love the fact that sometimes we wish we had a knife to clean our fingers, cut a rope, open a box, sever a thread. Now we do, always. Our new key knife just might save the day, unless of course, you lock it in the trunk.
