I see how that is possible, but I don't know if I'd be using any outboard clutch models when I'm away from vehicles, so I guess I don't have to worry about that. I can't pretend that I never get pinches, but it's rare enough that so far, each pinch has been one where I've been in a situation where I could change bars if the next guy/saw was far away. Point well taken though.
Plus, a pinch can be an early indicator of lost focus and/or reduced alertness maybe due to fatigue of the operator. The pause in cutting you take when changing a bar for this reason could be enough to consider whether you should continue or take a break to refocus or just call it a day if you have that option. Once you have some experience, pinches are very rare and therefore beg the question, "How or why did I let this happen?" and "Do I need to wake up?"
