Metcoid / Metal Engineering Co.

Tool advertisements for METCOID, a division of Metal Engineering Company of Chicago, begin appearing around 1950.  There are many "Metal Engineering Co" companies prior to this but we feel the METCOID associated company started about this time.

Metcoid Lever Jaw Locking Pliers. These are not as heavy as a pair of Vise-Grips and they don't have the release lever, but they are well made. Finish is a silver paint over steel.
