I made my dad a bottle opener for his birthday. I had a large piece of thin aluminum lying around, so I sawed out a rectangle and then filed down the metal to the correct shape. The lines were made using paperclips hammered into the aluminum, and the eyes were drilled gently. The mouth is shaped so that bottle caps easily fit inside and the body provides a nice handle for applying pressure. I also epoxied a small neodymium magnet to the back of it so that it serves as a fridge magnet!
You can see my original plan in the third picture.
