Always ask them about the back alleys, that's where the REAL stories are.

The 5,000 cycle rule came from the old days when click wrenches used a simple spring and ball bearing setup that wore out faster. Modern ones use a different internal design that holds calibration way longer. I've got a Snap-on that went 8 years without a recheck and still hit dead on when I finally tested it against a torque analyzer.

Hate when that happens but honestly you gotta respect someone who knows their stuff and takes the time to help out.
