A first end portion has an end face, a longitudinally extending face, and a first and a second recess 26 in one or more surfaces of the first end portion, and the first recess (24) is located on substantially the opposite side of the longitudinal axis of the elongate body to the second recess. Preferably the recesses are in the narrow edge of the blade and are engaged by two pins 58 68, one of which is fixed 58 and the other is moveable 68 e.g. screw thread. The pin may be vibration resistant. The blade may have a stadium or rectangular cross section and may be planar throughout. Also claimed is a handle for use with the blade, preferably having the fixed and mobile pins. It may also have multiple slots (44 46 Fig 8) for receiving different blades at different orientations.
