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 (an iron bracelet), Kachera (100% cotton tieable undergarment (not an elastic one)) and Kirpan (an iron dagger large enough to defend oneself).
