I'm in the camp of never getting pinched, but I just played around with one and can see how a finger with just the right of fat or maybe even looser skin could wrap around into the the void between the scale and lockbar when trying to push it over to close it, is this what we're talking about? I do agree a button implementation like the smock is a much more sophisticated design, wish it was on the PM2, M2, or more knives in general. Other wise I love me some mid lockbacks they may be an older design and less trendy these days but man are they sexy in the old tried and true 1911 firearm kind of way. And if you really want to get "fidgety" with them you can still snap them closed with your fingers out of the way just like an overrated axis lock that everyone's mom and dog likes to copy on these days.
