Actually, I've found that the tip of a ball point pen (eg, Staedtler
Stick- metal point-solid- Don't use a retractable ballpoint- they're too
flimsy) works fine- just stick it in the hole and pry
down a bit until the sSimm releases- do it on both sides and pull out.
The lever point tends to be close to the chip, unlike the Hex wrench,
and gives good leverage and not much motion of the point- just enough to
release, so you can't do damage as it releases.
