I would consider using the 'Did arrows survive?' rules from DF Wilderness Adventures, and add absolute value of half of bulk (round up) to increase their chances of survival/recoverability, since seems to me that it should be harder to misplace a harpoon than a shuriken


Cheap likely should impose a penalty on the survival check though. Since Cheap throwies are quite popular (its not like you want to parry with them!)
