When using one hand, the opening operation is that of what resembles the flicking of a Bic lighter- thumb on top of the grooved end (pivot) of the blade. The out and downward motion of the thumb will cause the blade to swing open in an arc. It is a bit clumsy for some. I' ve always used the forefinger (instead of the thumb) method to open. No problems.
