The "Finnish version" of the legendary P38 folding can opener. A damn nice thing to have when you come across canned food without ring pulls. These have a little hole for attaching to your dog tag chain. The blade locks in the open and closed positions for safe carry and easy use.

Finnish military surplus

These are all apparently unissued, but since they have been in storage for decades you should expect some tiny rust spots. Perfectly serviceable though!
