These are alligator forceps. I suggest these for anyone that uses test tube setups. This tool makes it super easy to take the cotton deep inside the test tube out. It is about 2-4 seconds to reach into the test tube and grab the cotton and pull it out with this, where it was a lot longer and harder to take it out any other way that I have tried. Yesterday I got the cotton out of ~150 test tubes in 10 minutes, I would never have been able to do that without it. Overall, this tool is just useful.
