unit tools
The various finishing tools which have some device
or design cut on the end of a brass shank. They
are used separately or in conjunction with each
other, as well as with line tools to form
patterns. They may be "solid" or "line" in form,
and when meant to be used by hand, generally do
not exceed 3/4 by 3/1 inch in size; otherwise they
become very difficult to use. A larger tool meant
to be used in a press or blocking device, is more
appropriately called a STAMP (2) . Unit
tools range in complexity from a simple dot to
very intricate lacelike designs. The use of unit
tools has declined in recent years, primarily
because of the different conception of design
prevailing today, but the same principle of
building patterns from separate tools in still
valid. (66 , 161 )
