Third installment of unidentified things. Expand my knowledge, if you can and would like to.

UPDATE: Kind reader James sent this:

Possible answers to unknown3 (#1 farrier rasp), (#3 looks like a farrier’s tool for scrapping under the hoof), (#8 it looks like a flint striker), (#10 handle for inspection mirror/retrieving tool “magnet” generally used in automotive).

Thanks, James!
