Knives
Safety first is important when it comes to potentially dangerous household items. You wouldn’t want to buy a knife and then slice your hand on it before you get back to the car. So some kind of protective packaging seems very sensible in this case.
Once again, though, we have a situation where the amount of packaging doesn’t really fit with the size of the object. Perhaps this packet was meant to be for a bigger knife, or the whole of the knife was meant to be inside it. Either way, something’s not quite right here.
