That's why Groot was able to lift the ax, not because he was worthy but because he didn't need to be. As viewers may recall, Groot was in intense pain when he merged the two parts of Stormbreaker together using an extension of his arm, something that Thor briefly warned of while aboard the Guardians' ship..
In this way, can Groot pick up Thor's hammer?
Thor's hammer Mjolnir was defined by the fact that only the 'worthy' could lift it – so basically no-one except the god of thunder (and Vision, for some reason). But when it comes to the weapon's replacement, Stormbreaker – which Thor forges in Avengers: Infinity War – Groot is able to lift it too.
Subsequently, question is, why does Thor have an AXE? Searching for a weapon that is powerful enough to defeat Thanos, he heads to Nidavellir, and meets Eitri, the original maker of his hammer. After explaining what is happening, Eitri agrees to help Thor and together they forge Stormbreaker, an axe that channels the power of the Bifrost. This is now his main weapon.
