File Card: Card Clothing Glued into a Recessed Wooden Handle (Nicholson, 1878)
A file card is a short wire brush for clearing the filings out of a file's teeth. In 1878 the Nicholson File Company described the usual home-made card, old card clothing tacked to a rough handle that often split and soon came loose, and sold a better one: new card clothing fixed in a recess in the handle with glue, so the glue holds the clothing by its edges as well as its bottom.
Nicholson gives no sizes, no wood and no recess depth; those are unknown here.

Using it
Using it
Clean a file at intervals while working and before it is put away: wood, horn and the like mix with oil in the teeth, bake hard when dry, and stop the teeth biting. Draw the card along the file to clear the filings. Pins stuck fast in the teeth are picked out with the soft-iron scorer, which is not built here.

History and honest limits
History and honest limits
Nicholson patented these file cleaners on 12 February 1878 and sold them by the half dozen, alongside a File Brush that combines a brush, a card and a scorer for tool makers using fine files.
The wood, the sizes and the recess depth are not given; a hardwood board stands for the handle wood. The scorer and its spring are not built here.
