ABSTRACT:
A tool set of the pivoted crossed lever type is provided with a pair of members pivotally and releasably connected to one another. The members may be biased, in effect, to an open essentially crossed position. Such a bias may be provided by magnetic poles of opposed polarity placed in juxtaposed surfaces formed on each of the members. The polarity of the magnetic poles may be switchable to enable the juxtaposed surfaces to be selectively attracted or repelled from each other.
