Kesh – uncut hair. Sikhs believe that hair, like everything else, is a gift from God, therefore it remains uncut.
Kanga – a wooden comb. Used for combing the hair and keeping it tidy and in place under the turban.
Kara – an iron bracelet. Serves as a reminder for Sikhs to follow the morals of their faith.
Kachera – a specific style of cotton underwear. Reminds Sikhs of the Guru's message regarding the control of the Five Evils.
Kirpan – a strapped curved sword. Symbolises the safety of all and the carrier's personal duty and responsibility as a Sikh to protect the innocent in the message of peace.
