From questing and gathering in WoW I suspect their drop rates are timed instead of just percentage based. I would frequently get a spike of drops and then nothing for a while and then another spike. If someone else is farming the same drops then my drop rate would go down even if my kill rate stays the same.

This is pure speculation and based on a gut feel from collection quests. If it is true though it means that the more people farming for the hilts the smaller your chance of getting one.
