Knack / jar opener

This jar opener is based on the principle of vacuum. You simply put Knack on the jar and bend down the lever. Thereby the holder is being sucked to the cover and the lever becomes a handle which can be easily gripped in order to turn the jar cover open. After the jar is opened you release the vacuum by lifting up the lever again. Knack – there is no need for big force as the vacuum principle does the trick – Knack’s easy principle will make many people enjoy this object in their every day life.
