The Five Ks

In Sikhism, the Five Ks (Punjabi: ਪੰਜ ਕਕਾਰ Pañj Kakār) are five items that Guru Gobind Singh commanded Khalsa Sikhs to wear at all times in 1699. They are: Kesh (uncut hair), Kangha (a wooden comb for the hair), Kara (a iron bracelet), Kachera (100% cotton tieable undergarment (not a elastic one) and Kirpan (a iron dagger large enough to defend your self).

The Five K are not just symbols, but articles of faith that collectively form the external identity and the Khalsa devotee's commitment to the Sikh rehni "Sikh way of life". A Sikh who has taken Amrit and keeps all five Ks is known as Khalsa ("pure") or Amritdhari Sikh ("Amrit Sanskar participant"), while a Sikh who has not taken Amrit but follows the teachings of the Sri Guru Granth Sahib is called a Sahajdhari Sikh.

The Kesh, or unshorn long hair, is considered by Sikhs as an indispensable part of the human body. Long known as a sign of spiritual devotion, it also emulates the appearance of Guru Gobind Singh and is one of the primary signs by which a Sikh can be clearly and quickly identified. A Sikh never cuts or trims any hair as a symbol of respect for the perfection of God's creation. The uncut long hair and the beard, in the case of men, form the main kakār for Sikhs.

The turban is a spiritual crown, which is a constant reminder to the Sikh that he or she is sitting on the throne of consciousness and is committed to living according to Sikh principles. Guru Gobind Singh told his Sikhs:

"Khaalsa mero roop hai khaas. Khaalsa mai ho karo nivaas... The Khalsa is my image. Within the Khalsa I reside." Wearing a turban declares sovereignty, dedication, self-respect, courage and piety.

A noted figure in Sikh history is Bhai Taru Singh, who was martyred but he refused to get his Kesh cut.

Comb the hair twice a day, covering it with turban that is to be tied from fresh.

A Kangha is a small wooden comb that Sikhs use twice a day. It is supposed to be worn only in the hair and at all times. Combs help to clean and remove tangles from the hair, and is a symbol of cleanliness. Combing their hair reminds Sikhs that their lives should be tidy and organized. The Sikhs were commanded by Guru Gobind Singh to wear a small comb called a Kangha at all times.
