Seriously people used a knife to pry out the pit...
Owning restaurants for decades we ALWAYS took the blade of the knife and basically slam it into the pit then twist easy peasy, HOWEVER I can see how home cooks could miss the pit with the knife and end up having stitches!!!
Not exactly. You take a sharp knife and ‘chop’ into the pit. That is intended to give you traction to twist the pit out. Only problem is that the knife may glance off the pit and hit the fingers of the hand stabilizing the Avocado. Any knife sharp enough to bit into an avocado pit will send you to the ER.
