Publisher's blurb: Locks need keys and, though many keys may be similar, some may not. A standard key has two main parts; the bow, by which the key is held, and the blade, the part that goes into the lock. Many of the keys described follow this standard form, but many do not. In the cases of those that don't fit this layout, their design is essentially an integral part of whatever lock they are intended to open. These are keys in the broader sense, as an item designed to open a lock, rather than items that follow a specific form. Some of the keys are probably magical in nature.
