The invention provides a tissue cutting device comprising a handle, a first blade, and a second blade. The second blade is coupled to the handle. The second blade is rotatable relative to the first blade such that the second blade is configured to rotate between a first position and a second position. The second blade is in a same plane as the first blade when the second blade is in the first position. The second blade is rotated into a different plane from the first blade when the second blade is rotated from the first position toward the second position.
