Knight of Swords

drive · directness · charge of the mind

Fast, fearless, unsubtle action on a conviction. It cuts through, at speed.

Reversed

aggression · haste · tactless

Force applied where precision was wanted; damage done in passing.

Why this astrology

The pips two through ten map onto the thirty-six decans, ten degrees of the zodiac each, so Knight of Swords is fire of air — a planet working through a particular third of a sign. Aces are the root of their element and the courts carry it as temperament.
