An implement for opening cans.
In-game description

A can opener is a tool that can open any food cans. Using a can opener instead of a knife or hatchet will allow the player to preserve those tools' condition, and is preferable to smashing open cans since it does not result in losing a portion of the food as spillage.

Each use reduces condition by 2%.

Repairing requires 1 scrap metal, restores 25% condition and takes 45 minutes when using simple tools.

Can openers are fairly common and can open fifty cans from full condition. Since scrap metal weighs less, it is preferable to scrap duplicate openers.
