Pictured are a fragment from a triangular file, half of a pair of scissors, and a schist whetstone used to sharpen edged tools. The paucity of other tools such as axes, scythes, etc. is most probably indicative of the fact that the house was dismantled versus being catastrophically destroyed. Dismantling the house would result in useful things being removed and reused in other household. When a house burns down or is otherwise suddenly destroyed, useful items are often left behind as opposed to having been salvaged from the debris.
