For General Knowledge:
The five Ks (panj kakaar) are five articles of faith which all baptized Sikhs (Amritdhari Sikhs) are obliged to wear. The symbols represent the ideals of Sikhism: honesty, equality, fidelity, meditating on God and never bowing to tyranny. The five symbols are:
Kesh: Uncut hair, usually tied and wrapped in a Dastar
Kanga: A wooden comb, usually worn under a Dastar
Katchera: Cotton undergarments, historically appropriate in battle due to increased mobility when compared to a dhoti. Worn by both sexes, the katchera is a symbol of chastity.
Kara: An iron bracelet, a weapon and a symbol of eternity
Kirpan: An iron dagger in different sizes. In the UK Sikhs can wear a small dagger, but in the Punjab they might wear a traditional curved sword from one to three feet in length.
