    Ric:

    Do you mean the Hart Spring Tool?

    In response to the notion of "bending" the springs, the mythology of
    the word would lead us in the direction of putting bends, and kinks,
    in springs instead of thinking of them as lever arms attached to the
    coil of the spring. The lever arm really shouldn't be "bent", but
    the coil can be eased or tightened by working in as close to the
    coil as possible on the lever arm of the spring. So grabbing the
    spring lever arm down towards the coil will be more quickly
    effective than in the middle. Strengthening them, like butterfly
    springs, requires working as close to the coil as possible so there
    no kink induced in the lever. We've all seen butterfly springs for
    the rep lever with 90 degree bends in them; in that condition, the
    only possible regulations are very slow or very fast--nothing in the
    middle.
