Joint Scrapper

Honestly, I feel like this tool doesn't have much to do with what we are learning, but It could be used as a source of metal. I walked around the store investigating different told and one of the workers came up to me and asked me if he could help me, I said sure I'm trying to find a tool that I have never seen before, sure enough he came back with this joint scraper in hand and said "I bet you've never seen this before."I said Yes sir, you are correct, what is it?" He man further explained it to be a Joint Scraper, it is used to remove the dirt, mud, excess grout, around corners and between tile or wood.
