A steel file blade and bone handle for an Inuit-adapted file made from salvaged material from the 1845 British Northwest Passage Expedition led by Sir John Franklin. The blade is of European manufacture and marked with the government broad arrow, the bone handle is an Inuit replacement. The end of the blade has been broken off.

The file was bartered from a group of Inuit by Captain F. L. McClintock's sledge team on 3 March 1859 near Cape Victoria, Boothia Peninsula. Here the sledge team met about 45 Inuit who bartered relics in exchange for knives, files, scissors, beads &c... In his appendix McClintock is more specific, stating 'two files.... One knife and once file are stamped with the broad arrow' [McClintock, Voyage of the Fox (1859), pages 232, and 369-70].

The knife has (7) painted in white on the handle, indicating that it was displayed at the Royal Naval Museum, Greenwich, 'Case 5, No. 7' but this was amalgamated with No. 2 'Files'. The item is shown in - 'Stereoscopic slides of the relics of Sir John Franklin's Expedition' photographed by Lieutenant Cheyne RN, at the United Services Museum, Whitehall, No. 10 (top left below handless file).
