Piston Ring Installation Pliers
To the untrained eye, this looks like a regular pair of pliers, but we can’t for the life of us figure out what the teeth are for. Also, the design is quite frightening, what with the elongated shaft that goes down and the stubby handles. To get the answers he was looking for, he uploaded an image of this frightening tool.
Thankfully, these aren’t dentist pliers. They’re not designed to take the teeth out of unsuspecting patients’ mouths. These are called piston ring installation pliers, which probably install pistol rings or something. Ask a mechanic, they can better explain what this thing does.
