Hook And Eye. A metallic fastening for garments, consisting of a hook, commonly made of flattened wire bent to the required shape, and an eye of the same material into which the hook fits. Under the name of crochet and loop, this form of fastening was in use in England as early as the fourteenth century. In this country all the hooks and eyes are made in New England, where until a few years ago they were fastened together and sewed on the cards by children at a few pennies per gross. They are put up one gross in a box and range in size from No. 1 small, to No. 10 large.
