A two-handed baton is shown constructed from a hollow cylindrical shaft having a first fixed handle at one end extending at an angle from one side of the cylindrical shaft and a second handle normally placed close to the first handle on the same side as the first handle and parallel thereto. The second handle is spring loaded to slide from its normal position at one end of the cylindrical shaft next to the first handle toward the opposite end of the cylindrical shaft.
