"Beam-type torque wrenches do not require calibration; they are 4% accurate by deflection or BROKEN should the beam become bent. No middle ground."
This statement is false. I won't get into the specifics of how a beam type wrench can be outside of +/-4%, but they are numerous. Most beam type wrenches can't even resolve 4% throughout the calibrated range, so operator interpretation will already exceed 4%. And exactly how much QC do you think is applied to a torque wrench being manufactured for less than $10?
Calibrating a torque wrench with another torque wrench is also extremely bad practice, for reasons I thought would have been obvious.
