Review on ABN Hose Pincher Pliers Set: 3-Piece Automotive Crimping Pinch-Off Tool for Radiator, Coolant, Heater, and Fuel Pinch by Terry Brendemuehl

As others have said, the difference between the three pliers is negligible (other than the length); So buying three didn't help much as I'll probably never use one if not two of them. However, the design seems quite elaborate, so that's a plus. Update - after trying all three pliers on a hose less than an inch in diameter, none of them could pinch it and the pinching parts turned away. uneven contact with the hose. These will definitely come back. Pure garbage. Worst of all, I've started the job and can now finish it, so I'm out of transport until I get a decent pair of hose wrenches.
