INVENTION AND DISCOVERY.

POCKET-KNIFE.—Here is an excellent thing in pocket-knives.

Attached to the handle is a revolving plate which, when the knife is opened, turns round and catches the blade firmly, making it impossible for it to close and holding it absolutely rigid.

So many accidents have occurred through the slipping of the pocket-knife that it seems strange such a simple device as this should not have been thought of before.

We are aware that there have been several knives made with springs to hold the blade firmly when open, but these have all been large and clumsy knives, whereas the one illustrated is really what it pretends to be—a pocket-knife.
