The last of the ten Gurus, Guru Gobind Singh, asked Sikhs to wear or carry five special things to mark them out as the khalsa. All five of these symbols start with the letter K, so they're known as the five Ks.

A kanga is a small wooden comb, used to keep all of that long hair clean and groomed.

A kara is a bracelet made from steel. The circle reminds Sikhs that God has no beginning and no end.

Once Sikh men have been baptised they wear special underwear, rather like long boxer shorts, called kacchera or kaccha. They're very like the underwear warriors used to wear at the time of Guru Gobind Singh.

A Kirpan is a sward. These days baptised Sikh men and women carry small kiprans as a symbol of self-defence and to remind themselves that they are meant to stand for fairness and justice in the world.

The word kesh means hair. Sikhs believe they should never cut their hair, which signifies that they live according to the will of God. Because their hair is long Sikhs tie a turban on their head to keep it tidy.
