In Avengers: Infinity War Thor throws Stormbreaker at Thanos, while Thanos uses an Infinity Stone to counter Stormbreaker but fails to stop it.
How did Stormbreaker withstand the power of an Infinity Stone?
Shadow Wizard answered it quite well but in writer's own words:
When asked how can Stormbreaker overpower the power of the completed Infinity Gauntlet, writers Christopher Markus and Stephen McFeely suggest that Eitri is responsible because of his "Dwarven magic": He made both items and made it so that Stormbreaker is able to defeat the Infinity Gauntlet. - wikia
