They are used heavily in aviation maintenance. They use them for large air, hydraulic and fuel couplings. They are a cam design, so they hold very tight, and I have never even felt then come close to losing grip or rounding corners. Do not think of these as or similar in any way to channel locks, other than range of adjustability. They came highly recommended by the engineers where I work. I bet there isn't a day that goes by that they don't use them.
