3-jaw rivet guns? (or: "Ping Andy Dingley!")
Speaking as an aircraft engineer, most of our pop pliers are the
standard 2 jaw. Lazy tongs are 3 jaw.
The pop pliers have a small range of rivet size options in terms of
dia, or you need to change the jaws. The lazy tongs take a far greater
range of rivet mandel sizes with the same jaw.
Most pneumatic pliers are also three jawed
