FILE FILOSOPHY
Flat Shoe Rasp. A form of shoe rasp but little
called for.
HAND File. Section, 1" advance on Flat. Par-
allel as to width, taper in thickness. Double cut
bastard mostly, though many second cut and smooth
and dead smooth. Length, 3" to 16".
Use: This file is preferred amongst machinists and
engineers for finishing flat surfaces, and owing to its
shape and its having one safe edge, is particularly
useful where the flat file would not answer.
PILLAR File. Parallel as to width, taper in thick-
ness. Double cut, same as Hand. Length, 6" to 16".
Use: For general machine-shop use on narrow work.
Cotter Blunt, Cotter Taper or Taper

cipally used in filing grooves for cotters, keys or wedges.
