The lever spring is a component that can stand out for its very high quality in the artisanal method. It can be bevelled at the top and bottom and sometimes have a space under the blade to prevent it from marking the mainplate.
For the semi-artisanal method, the lever spring can be made by stamping or electroerosion. In this case, it will be decorated more summarily.
Lever springs can also be manufactured in a simple, industrial way. In this case we talk about a wire spring.
