I know that Sri Vaishnavas worship Sudarshana Chakra, giving it the status of an azhwar. Does any other sect do so ?
In south India, Vel (the weapon of Karthikeya) and trishul are installed in some Karthikeya and Shakti temples (near the respective vahanas) and are worshiped but not as a god/Alzhwar like Sudarshana. Sudarshana is also called Ayudhapurusha and sannidhis for him can be found in Vishnu temples like Varadaraja temple in Kanchi and in Srirangam.
