Abstract This chapter reviews the experimental properties of shears bands. The most puzzling characteristic of these structures is the emergence of rotational-like behavior while the nucleus retains a small quadrupole deformation. Regardless of the details of particular theoretical models, it can be shown that the most important degree of freedom in describing the shears mechanism is the shears angle. It is then possible to develop a semiclassical description of the shears mechanism, in which the nature (multipole order) of the interaction between valence protons and neutrons constituting the shears "blades" may be derived and the dynamics of the system described. We discuss the competition between the shears mechanism and collective rotation and mention the connection to "magnetic rotation." Directions for future theoretical and experimental efforts are suggested.
