A shaping tool shapes a smooth bone cement surface, in particular for implantation of an artificial acetabulum. The shaping tool has a curvature, whereby the shaping tool has a curved base body and at least two layers, whereby a first layer covers the curvature of the base body at least in part and is connected to the base body in a detachable manner, and a second layer covers the first layer at least in part and is connected to the first layer in a detachable manner. The shaping tool is usable to pre-shape a bone cement for insertion of an artificial acetabulum.
