hardy tools fit in an anvil , some are for cutting , bending . shaping and such. look them up.. they go back hundreds of years and are still made and used today. often the detectorist needs to date a site by what he digs. .
same thing with the horse bit , been around hundreds of years but still made today.
but for the sake of a guess I'd say mid 1800s on both finds.
hopefully you will get some coins or buttons from the site to narrow down a date for you.
