Always be prepared with the new Key file. This is the first lockback 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 file might just make your day, unless of course you lock it in the trunk.
