Rather than dragging anything that belongs to you along the blade, turn the
blade crosswise to your thumbnail and, with the blade at about a ten degree
angle from square to your thumbnail, just drop the blade down onto the nail
gently, moving it slightly toward you. If it's truly sharp it will catch on
the nail; it it's anything less than sharp it will skid.

works the same with a plastic ball point pen. the steeper you can get the knife
to catch the sharper it is.
