A copper alloy model tool (one of a set of five W130–W134). The practice of placing metal model tools in tombs becomes prevalent in the Old Kingdom from the Fourth Dynasty. These tools are made of sheet metal, and often contain arsenic, suggesting that either these models were made from other melted down tools, or the silvery quality of arsenic could have been considered attractive (it would have been easier to make such tools from pure copper). The set was purchased by Wellcome from the Rustafjaell collection in 1906.
