This is a great Man Cave item if your decor is automobilia or petroliana. Back in the day, this was a great tool for putting oil in your automobile from metal or metal top quart sized oil cans. You would set the oil can on the trough above the funnel, put the funnel into your engine, pull the trigger, which would push the can down onto the can opener, and the oil would run through the funnel an into your engine. Very clean and efficient. Call .
