It is part of what tarot card readers call the "Minor Arcana".
[1] In English-speaking countries, where the games are largely unknown, tarot cards came to be utilized primarily for divinatory purposes.
[1][2] The King of Swords card from the Minor Arcana is often used to depict a mature man with sound intellectual understanding and reasoning.
This card depicts a man who is strong-hearted, decisive, and intellectually oriented.
The King of Swords can also depict a man who is ruthless or excessively judgmental; the querent is therefore advised to balance their intellectual orientation with emotional understanding.
