These small files are available from Frei and Borel in Oakland, and
they come in two styles: 'Joint Edge' files are parallel flat files
(like an equaling file) with round edges, item # 131.537 to 131.546.
'Crochet' files are flat files with round edges, which taper to a
point (like a barrette file) item # 131.047 to 131.054. Each style
is available in different lengths and cuts (coarse to fine).
