Sounds like you two are onto something. If rabbits are going to spook easily, then it would be nice to have a way for new players to kill them at a distance so they can still be used as a source of food. Enter: The rabbit stick. To craft a rabbit stick you need a... stick. Go figure. In it's simplest form a rabbit stick is a stick about the length of your forearm and big enough around to have sufficient weight to kill small game. You throw it sidearm at your quarry and hope that it gets cracked with one of the ends as it spins around. A hit either kills instantly or maims the target so it is easy to finish off at close range. it would only be useful for small game in Haven and Hearth because you can only hold one at a time and only rabbits and chickens will go down in one hit.
The boomerang would also fall into this category, but I think it is hardly appropriate for the game's setting.
