An expandable baton includes a plurality of sections adapted to be stowed in a nested, collapsed position. The sections may be opened by swinging the baton in a whipping action into a locked extended position. Each of these sections may be made of similar or dissimilar materials, with the tip section having at least a portion being made of a relatively high mass material to preserve strike force when used in a whipping motion and the largest, handle section being made of a lightweight material to reduce weight of the overall baton. Intermediate sections may be included and may be made of either the lightweight material or the heavy mass material, as desired, taking into consideration force requirements in combination with overall balance and weight objectives.
