Weak
You have two bows but they're both covered in ice. This has made them very weak.

None
You take the bows out to your car, which is stuck in a bunch of ice and snow, and try to use them as a kind of weak jack (じゃく). You know, to get your car unstuck. Unfortunately, your bows are too weak and brittle to use as jacks, and they just snap in half.
