A fence panel, comprising:
- a rectangular mesh body, with first and second opposed parallel horizontal edges, and third and fourth opposed parallel vertical edges,
- wherein the mesh body comprises a plurality of lengths of razor wire arranged to form a plurality of diamond-shaped mesh apertures, each aperture having a vertical major axis of length Land a horizontal minor axis of length L/2,
- wherein the lengths of razor wire are fixed to one another at respective junctions,
- wherein the junctions which are closest to the first edge are spaced apart from one another and located on a line which is parallel to and spaced from the first edge by a distance D such that free ends of the razor wire extend as projecting portions from said closest junctions by a non-zero length,
- wherein the projecting portions include at least one barb between the line and the first edge, and
- wherein 0<D≤0.25×L and L≤200 mm.
