<p>A knife, such as a surgical scalpel or a handymans knife has a protective blade cover (3) moulded integrally with the handle of the knife. The end portion of the knife and the cover are both formed in mating halves about a common fold line and the knife blade is secured by folding the halves over each other to trap the blade and securing, as by welding. The cover has a part-circular recess (5) to receive a part-circular tip (7) at the end of the handle. The knife and cover are connected together only by a frangible web between the recess (5) and tip (7). When the web is ruptured for first removal of the cover, the tip (7) has snap-fitting engagement in the recess (5) to permit replacement and retention of the cover.</p> |
