Abstract: A portable device for shaping an edge of an aerofoil comprises a housing, a cutting tool mounted in the housing (the cutting tool having a cutting edge to remove material from the edge) and a plurality of guides mounted in the housing, so that in use the aerofoil engages with the guides to locate the edge of the aerofoil relative to the cutting edge and to permit movement of the housing in a cutting direction so as to remove material from the edge of the aerofoil. The device is characterised in that the cutting tool is mounted so that in use the cutting edge can move relative to the edge of the aerofoil in a direction generally perpendicular to the cutting direction.
