    1. Cutting action of cross-cut saw teeth
      When cutting across the grain the teeth of the saw must be shaped in a manner that they can sever the fibres on each side of the saw kerf. For this to happen, adjacent teeth are brought to points on opposite sides of the blade. The points and knife-like edges on the teeth cut the fibres forming a kerf. The teeth are set to provide clearance for the blade in the kerf. The front of the teeth are inclined at about 70-80 so that they do not burry themselves in the fibre.
      Any 6 x 1-6 marks
      1. Book matching
        A book match uses successive leaves of veneer
        Every other leaf is turned over like the pages of a book, and edge-joined in this manner.
        The reverse side of one leaf is the mirror image of the succeeding leaf. The result is a series of pairs
      2. Slip matching
        This match is used to create a wide veneer from narrow ones
        Consecutive vencers are slipped sideways and edge-joined together without altering their grain direction. This provides pattern repetition.
      3. Diamond matching
        The sheets are cut at an angle and quarter-matched to produce a diamond figure. The sheets are matched with a common centre, joined side by side.
