I think i can say this without spoiler tags, as it relates more to Ragnorak. Hela was able to catch and crush mjolnir because her magic rivaled Odins, the person who put the enchantments on mjolnir to begin with. If her magic was equal to or better than his, which i believe they explained it was while she is in Asgard (she draws energy from it), then she can cancel out the enchantments and its just a hammer.
For anyone else to have that ability would require some explanation, especially if they didnt have any infinity stones....
Stormbreaker is supposed to be the strongest weapon in all of Asgard, be indestructable, summon dimensional energy, amplify Thors energy, and summon the bitfrost.
If somebody had a weapon that could hold up to and easily deflect stormbreaker, it would require at least a 30 second explanation, as it would be the strongest weapon in the universe we would have been exposed to, short of the combined infinity stones.
