An elegant pocket knife was once as much a part of a gentleman's basic equipment as the jump-lid watch in his waistcoat pocket. Pocket knives are also useful helpers in modern, digital everyday life, because no app, no matter how cleverly programmed, can open blister packs, peel a pear or cut a thread from the hem of a jacket. But which pocket knife does the man of the world carry today? The usual gentleman guides are silent about this practical utensil. This book closes this gap. It provides a representative overview of fine pocket knives in traditional and modern designs. At the same time, it provides a lot of interesting information about the history and technology of pocket knives.
