Sentimental value

The thing is that you aren't supposed to remember the sentiments it should bring, anyway. Plus, since no one knows where they get all those weapons from, it could as well be the same sword. It's just a matter of your character saying that somehow they felt attracted to that specific sword by a feeling they can't explain.
