This British Standard classifies types, and specifies
certain dimensional aspects, of taper-ground and
flat-ground hand saws for cutting timber. The
hardness level and finish of the saw blades is
specified and tests are included to verify the qualities
of the complete saw.
Four classes of hand saw are specified, and in each
class, saws from 450 mm to 660 mm in length are
available.
This part of BS 3159 distinguishes between saws
intended for ripping and those for cross cutting.
