And the theme for this thread for the average home mechanic is pro level tools aren't necessary for those that don't wrench everyday.
Thousands of bike shops throughout the country have the following wrench laying around those that professionally build the highest end carbon road bikes on the market.
A shop may order 10 of these wrenches. Some mechanics may prefer their own type of torque wrench.
Is the precise calibration of this wrench perfect? No, it has some error. Is the error acceptable? Yes and why they exist and so commonly used with good result.
