Answer:
Knife: If the shape inside the seed is that of a knife, it is believed to mean the winter will be cutting cold. As my grandma would say: So cold the wind feels like its cutting right through you like a knife.
Spoon: When the shape inside the seed looks like a spoon it is said to mean it will be a heavy winter. The spoon represents lots of shoveling.
Fork: The appearance of a fork shape within the seed is believed to mean that winter will be easy with only a light dusty of snow
