FILE FILOSOPHY
Use: In machine-shops quite generally for filing
internal angles more acute than the rectangle, clear-
ing out square corners, filing up taps, cutters, etc.
Handsaw Taper or Taper Single Cut.
Tapered to a small point. Single cut, second cut.
Length, 3" to 10". f
Use: As their name implies, much the largest use
of these files is in the sharpening of handsaws, which
makes them one of the most generally distributed
of any file made.
The Handsaw and Three-Square File, while both
made from the three-square section, are different in
the respect that, in the saw files both single and double
cut, the edges before being cut are set to give them the
proper bluntness for durability; in the Three-Square
File, the edges are left very sharp and not cut, thus
making them entirely unfit for the purpose of filing
saws.
Handsaw Taper Double Cut or Taper
DOUBLE Cut. Double cut, second cut. Length,
3" to 6". Use: They are preferred by some in filing
