What sword does Sonic have?

Sonic the Hedgehog is primarily known for his speed and agility rather than wielding weapons, but in some adaptations, such as the comic series by Archie Comics and IDW Publishing, he has been depicted with a sWord called the "Soul Emerald SWord." This sWord is often associated with his adventures in a fantasy context. However, in most of the mainline games and media, Sonic does not use a sWord, focusing instead on his abilities and speed to overcome challenges.
