Improvements relating to trowels
A plastering trowel 1 for flattening and smoothing finish plasters, the trowel comprising a blade 5 constructed from a flexible sheet material, a central spine 4 for stiffening the trowel and a handle 2 connecting via the spine to a central region of the blade. The blade defines a pair of peripheral ends 10, 11, the thickness of the blade tapering from the central region to the ends. The blade is machined during manufacture. The blade may have friction-reducing indentations 12 defined in the working face of the blade which may be pits of grooves oriented parallel to one another, with a depth of less than 1mm. Further disclosed is the blade of the trowel, and a method of manufacturing the blade comprising reducing the thickness of the blade at the ends and forming the indentations.
