In Animal Crossing: New Horizons there is an item called iron nuggets. The only way I've found to get these is to hit rocks with a flimsy axe up to 7 times once a day, and they seem to have around a 20% drop rate. I haven't been using them and have instead been saving them, but I don't have the 30 required to progress in the story yet. Nook Mile tickets may yield a few of these, but without a ladder some parts of the islands are inaccessible to me, therefore spending miles to get tickets at the moment is inefficient. I know you can shake any tree infinitely to get more tree branches; is there some infinite way to get iron nuggets as well? Early copies help me out.
