Pināka (Pinaka), the bow of Śiva (Siva),  is also known as ‘Ājagava’ (Ajagava). This is called ‘Ajakava’, ‘Ajakāva'(Ajakava)  or ‘Ajagāva’. The way the word ‘Ajakava’ has been analysed in Śabdakalpadruma, seems to indicate that the ‘ka’ has been transformed into ‘ga’ through linuisic evolution. The Puraṅa-scholars  state that ‘aja’ refers to Viṣṇu (Visnu) who is beyond birth, and ‘ka’ refers to svayambhū (svayambhu, self-emerged) Brahmā. When Śiva set out to fight against Tripurāsura (Tripurasura), with his bow ‘pināka’,  Brahmā (Brahma) and Viṣṇu inserted the melody of their Śivastuti (hymn to Siva) into that bow. So this bow came to be known as ajakava. In Mahābhārata and the Purāṅas as well, Śiva’s bow has been mentioned as ‘ājagava’. Scholars also argue that, this kind of bow was made of the horns of gava , that is, cattles like cow and buffaloes and the skin of aja (goat). Perhaps this technology was first used for making the bow of Tripurāri Śiva ( Tripurari Siva, the enemy of Tripura). King Pṛthu( Prithu) got this bow. It is also said that  In Mahābhārata, it is said that the Ikṣvāku (Iksvaku) king Māndhāta’s(Mandhata) bow was also known as Ājagava. These bows were as strong as Śiva’s Pināka, and that is why they were also famous as Ājagava. King Sudyumna of the Ikṣvāku clan and the sages Nara-Nārāyaṅa (Nara-Narayana) also possessed the Ājagava bow.

It is notable that the bow of God Sri Viṣṇu (Visnu) was named Śārṇgarava (Sarngarava). In this case as well, the śṛnga (sringa; horn) of cattles had been used for making the bow. So, by name, Ājagava and Śārngarava have a similarity which also denotes the similarity in the technology of their making.
