Description
A straight Morse key that uses any teaspoon between 130mm and 150mm as the lever arm, and a rubber band as the spring. The head of the spoon rests on a replaceable bearing surface, on which is can slide of flex to give the lever action. A magnetic contact connects the wiring to the back of the spoon; pressing down on the handle completes the circuit.
