TBH, i have a couple sets of those, seems like one of 3 things happen
I have to rock the chip out, and with those salad tongs I have squat feeling or control and I bend a pin
Trying to pull them directly out usually makes me punch myself or something near by as your arm goes flailing around with more than 100lbs of force once it pops free
they slip and crack the edge of the chip, I wouldn't bother unless you got a little pc kit or something that came with them
