Re: bolt handle/torque wrench
no one makes one of these at current. The belief that someone does is a great mis-direction of a video Lowlight posted, in which for some reason the rings made a 'click' sound and lead several people to belive it was in the bolt knob and was a torque click. That is not the case, and I think developing a torque bolt know, while not impossible, fits well beyond the realm of practicality.
