All you need for this instructable is a spoon and some tools to bend it with. I started with a large soup spoon, thinking that I would want the larger surface area and length. The results was not great, due in part to the weight of the head, making the whole rig rather unstable. The best result was obtained from a cheap dessert spoon. This was easier to deform and not as top-heavy.
"Locking sheet metal tools" provide more control. Otherwise use what you have at hand. If you live in the Matrix, then use your mind.
