Static spine describes the flexibility of a shaft when we test it without shooting it.

Usually by bending it in the hands to get a feel for the degree of stiffness, or by the accepted method of suspending a known or standard weight from the mid-point of a given length of shaft and then measuring the deflection of the shaft.

Dynamic spine is simply the term used to describe the reaction of a shaft to the forces applied by shooting it from a bow.

In discussion of arrow shafts the terms stiffness and spine are commonly interchangeable, which should be clear from the context in which these words are used.

It's meant to be simple, not easy.
