Upright:

The Knight of Swords is all action and energy. He moves forward without consideration of danger or consequence. He can be too single-minded in his focus on attaining a goal or finishing a project. Great ambition and determination are associated with this card.

Inverted:

Inverted, the Knight of Swords is an impulsive whirlwind of energy and hype. They are full of ideas and action but have very little preparation or follow-through. They are likely to act without regard for consequence and as a result failure follows the many exciting projects they are involved with.
