My pickaxe mining animation isn't working, and the real anim is glitchy in game

I have a few issues that relate to my animation, which make me worried about how I would do things like two handed carrying of weapons.

Basically, I was attempting to show the product when the items were welded, but they aren’t. Usually, the pickaxe would move along with the anims, pretty well. Although, once I put it on to actually work, it’s very wonky and buggy and I don’t really know what to do with the welds since it makes the animation like that, and the pickaxe doesn’t even move in the active animation.
