If you put through top it will stop on second notch right before extrnder goes full round. Picture shows what part it stops.
But if you just put fully in and and close Skeletool it will bit strech carabiners side but it doesnt actually affect usability of carabiner and it looks like they actually tought that when they made carabiner that is so open.
But if that concerns you i would use method where you just slide it o top when Skeletool is closed, it still gives same usability as using it fully deep. And if you somehow manage break bitdriver with that technique you allready misused whole tool cause it needs quite force to break.
Only Tools Matters
