The Sikh look or Khalsa identity was given by the 10th Guru, Guru Gobind Singh, so that Sikhs can represent their values and the look of the Guru himself.There are five symbols of a Khalsa -- 1) Unshorn, uncut hair - signifies accepting the will / seal of the Guru. 2) A small comb for hair - signifies cleanliness for uncut hair. 3) A steel bracelet - can be used for combat. 4) Kirpan - sword, small dagger; 'kirpa' means mercy and 'aan' means honor. It is used to protect oneself and the needy but only in extreme situations. 5) Kachera - helps in better movement during combat. Originally, the 5 Ks were gifts from the Guru; we do not believe in ritualistic items. Every Khalsa is a Sikh, but not every Sikh is a Khalsa. It is similar to baptism. A turban is used to cover uncut hair and later became a part of identity. It is not compulsory to look like a Sikh to be a Sikh, but people often use it as an excuse to follow their own mind or mix Sikhi with other faiths.
