TM 9-243 TYPES AND USES - Continued TWO-MAN  CROSSCUT  SAW shape to other hand saws except it is usually mounted higher.  Backsaws  are  used  for  general  bench  work  such as cutting joints and smaller sections of lumber to length. Sizes vary depending on design and nature of work. NESTED SAWS The  two-man  crosscut  saw  is  5  to  6-1/2  feet  long  with a handle  at  each  end.  As  with  the  one-man  crosscut  saw, it also has a high-grade steel blade with the “cutter” and “raker”  teeth  arrangement.  It  is  used  when  two  men  are required for extra heavy cutting jobs. BACKSAW Nested  saws  consist  of  a  wooden  handle  to  which  sev- eral  different  blades  can  be  attached,  making  up  differ- ent  types  of  saws  such  as  the  keyhole  or  compass  saw. A slotted end at the heel of each blade slips into the pistol-grip type handle where a wingnut fastens it in place.  Nested  saws  are  used  to  cut  along  curved  lines, to start cuts for larger saws, or to make starting saw cuts from drilled holes or small openings. The size of these saws will vary depending on design and nature of use. KEYHOLE  SAW The backsaw has a straight blade and parallel top and bottom, with a heavy strip of steel or brass wrapped along the back to provide rigidity. The handle is of similar The  keyhole  saw  is  the  smallest  type  of  nested  saw.  Its blade has a very narrow point small enough to enter a 1/4-inch  hole.  It  is  used  for  close-quarter  work,  such  as cutting, shaping, or enlarging holes in a board. 46-3
