But not all signs are articulated with one single hand, many are executed using both. See the two examples:

    "Bicycle"
    "Party"

In the first sign it is both hands that move. In the second only the active hand moves while the passive hand remains static.

Signs using one hand are called one-handed and signs using both hands are called two-handed.
