A shoehorn (sometimes called a shoespooner) is a tool that lets the user put on a shoe more easily. It does so by keeping the shoe open and by providing a smooth surface for the foot and the heel to move, without crushing the shoe's counter (the vertical portion of the shoe that wraps around the back of the foot), in this way acting as a first class lever. - Wikipedia
Update: There actually was a single shoehorn instructable.
Step 1: Flatten the Spoon
Later on I'll use a small ball pen hammer to pound in a curve. I drew lines on the spoon with a marker to show you the hammer pattern I used.
Step 2: Heat and Curve
Place the spoon over the socket and hammer the sides down so they conform with the curve of the socket.
Once the spoon is curved, mount a ball peen hammer in the vice and use a smaller ball peen to leave a hammered finish. Make sure to follow the hammer pattern shown in step one.
Step 3: Form the Hook
Once you're done, hand bend a curve into the entire shoe horn.
