The word "Sahibzada" means "son" in Punjabi and is a term commonly used to refer to the 4 sons of Guru Gobind Singh, the tenth Sikh Guru. The word is a traditional word not used in the everyday language of today. The plural of the word is "Sahibzade" with a stretched "A" sound at the end.

The younger pair, called the "Chotta Sahibzade" were martyred together by the Mughals in Sirhind at the tender age of 6 and 9 years old. The older sahibzade, called the "Vaada Sahibzade" died fighting the enemy of many thousands at the young age of 18 and 14 years old in battle at Chamkaur Sahib.

They formed the nucleus of the Khalsa, as the first batch to receive khanda di Pahul, i.e. rites of the two-edged sword.

Gatka

Gatka (Punjabi: ਗਤਕਾ gatkā) is a traditional South Asian form of combat-training in which wooden sticks are used to simulate swords in sparring matches.In modern usage, it commonly refers to the northwestern Indian martial arts, which should more properly be called shastara vidiyā (ਸ਼ਸਤਰ ਵਿਦਿਆ, from Sanskritsastra-vidya or "science of weapons"). In English, the terms gatka and shastar vidya are very often used specifically in relation to Panjabi-Sikhs. In actuality, the art is not unique to any particular ethno-cultural group or religion but has been the traditional form of combat throughout north India and Pakistan for centuries. Attacks and counterattacks vary from one community to another but the basic techniques are the same.This article will primarily use the extended definition of gatka, making it synonymous with shastara-vidiya.
Gatka can be practiced either as a sport (khel) or ritual (rasmi). The sport form is played by two opponents wielding wooden staves called gatka. These sticks may be paired with a shield. Points are scored for making contact with the stick. The other weapons are not used for full-contact sparring, but their techniques are taught through forms training.The ritual form is purely for demonstration and is performed to music during occasions such as weddings, or as part of a theatrical performance like the chhau dance. A practitioner of gatka is called a gatkabajwhile a teacher is addressed as Guru or Gurudev.
