The present disclosure provides a clipping tool for clipping flash from a component e.g. a gas turbine aerofoil body. The clipping tool includes a riser having a support surface for supporting the component and a punch for gripping the component on the support surface such that the flash projects laterally from the riser and the punch. The clipping tool further comprises a tool body having a clipping aperture opening to a channel within the tool body. The channel is defined by a channel wall. The riser and the punch are translatable to shear the projecting flash from the gripped component. At least a portion of the channel wall within the tool body comprises a broaching surface having at least one projection, said projection reducing the cross sectional area of the channel to less than that of the clipping aperture.
