The fineness of sandpaper is indicated by numbers—00 (the finest), o,5, I, 12, 2, 23, and 3 (the coarsest). A size coarser than I3 is seldomneeded. For most work a sheet can be torn into four parts, by means ofany straight edge. For a fiat surface fold the sandpaper over a fiat block of cork orwood perhaps 4 or 5 long, 3 or 4 wide, and i thick (Fig. 205),with the edges slightly rounded. After using the block, finish withthe paper in the hand (Fig. 206). For an edge the block should benarrower than the edge (Fig. 207). If the surface be curved, a blockcurved correspondingly should be used. A piece of thick rubber orleather which can be bent is good for curved Fig. 205 Common Tools and Their Uses 79 Care should be taken not to round the corners and edges of thework, since the paper cuts more near an edge than on the middle of
