"Airbus and Boeing planes are assembled with Stahlwille torque wrenches."

I build 777's and use mostly Snap On torque wrenches that are calibrated regularly. My point is I will never meet the end users of my work yet they count on it getting done correctly with trustworthy processes. I would not use a harbor freight wrench there and I will not use it for my own personal needs either.
Those Stahlwille may be used in certain areas but not where I work. Those prices would chock a bean counter on the spot.
