Hammer

Reach the first Hammer by swimming to the far side and following the pipe into its room, then break the rusty grate for a shortcut.

Find the Pickaxe in the prison spider area, follow the key landmarks and reserve an Iron Rod for the Fix Lever on the way down.

Recognize the Axe on a low stone plinth in the cave and use it to cut roots in Deep Dish Dungeon.

Find the Silver Dagger beyond the Jaguar Door and prepare the three Key Pieces needed to reach that room.
