United StatesI am a machinist and am constantly getting little metal splinters. I purchased these when I started a new job as a little treat to myself. I bought these first, because they are American made, and their performance, looks, and functionality have been worth the money so far. I carry them with me basically every day, unless I’m doing something athletic and don’t have the pockets or its just not convenient. I would recommend these. The little leather case is also a nice little bonus as it makes it so they (the tweezers) don’t poke you, tear your pockets, or jab your hand when you reach in to get them. Although not usually in the same pocket, I’d imagine it would keep them from getting tangled up in your keys as well. As far as using them for grooming, I have pulled out a few wild eye brows, and an extra long nose hair or two. While this isn’t my primary use, I can tell you that the tip does get a good grip if that is what you’re looking to do.
