The crutch or ski stick has a flexible handle which can clip onto another similar crutch or stick to retain the two together for storage. Alternatively, the crutch can have a magnet or hooked pile fastener material to retain it to the other. The handle can be shaped or have grooves to allow ease of interlocking and release. The crutch can use the arm rests for interlocking.
