A can opening device with a built-in pouring spout that can be affixed to a can of engine oil for use in transferring oil from the can and is equipped with a punch that can be manually operated to open an air vent in the wall of the can. The device has a cutter of conventional type for cutting a pour hole in the top of the can, a conventional guide of the sort that rides against the side of the can to guide the cutter in its cutting operation, and a pouring spout shaped to serve as a handle for use in forcing the cutter through the can top. The punch is pivotally mounted on a metallic arm that is secured to the pouring spout, which arm is bent to extend diametrically across the top of a can to which the device is attached, from the pour hole formed by the cutter, then down the opposite side of the can to a point near its bottom end. The punch has a pointed claw at its forward end and is formed with a handle by means of which the claw can be swung into piercing contact with the wall of the can to form the above-mentioned air vent. The resulting air vent is in that part of the wall farthest removed from the pour hole in the top of the can.
