Tools

Tools include cameras, instruments, measuring equipment, repair devices. A person operates a mechanism or extends a practical capability through them. Staff record operation, maintenance, modifications, demonstrated techniques, the account of earlier use.

The deposited camera may have remained unused for years. A visitor can demonstrate a modification or discover a physical limit while making a photograph. These acts provide different evidence from an account based on appearance. A proposed repair requires another decision because it changes material condition and possible historical traces.

Staff can document skill through a specific demonstration, compare its relevance to a custodian's question, offer a complementary encounter. A tool may also carry a memorial or inheritance role. Material resistance, repair, evidentiary use develop those differences.
