Stone skin dresser or scraper.* Fide donor GTE: Stone skin dresser. Skin scrapers are found in great abundance about old camps and former living places. They are of various sizes and material. They were of the chipped basalt used for arrow and spear blades; chipped to convenient shape, or of sections of quartzite pebbles split along one face and chipped as required. Some of these were used as hand implements for scraping or softening the skin of the animals of the country, for articles of clothing, while others likewise used were set in the split end of short wood handles and lashed securely by means of hide, root or sinew. They are still used. *Information is from the original accession ledger.
