marvel - Does Stormbreaker have the same worthiness specifications as Mjolnir?

I've seen several references to

Groot

being worthy because he is able to handle Stormbreaker. However, to my knowledge, there is no mention of Stormbreaker having the same requirements of worthiness to wield as Mjolnir did. Have there been any explicit statements on the matter?

Answer

No, Stormbreaker does not have the worthiness requirement.
