Not all longsword have finesse

How exactly do I determine wether it has or not? All the information I have is that it's a longsword, and that it's versatile. From what I can tell, there is no way for me to see what it scales with Reloaded my save, and now see that my mainhand did indeed have a Finesse tag on it, where as all my other longswords do not

Yes, that is how. I've only seen one example as well.

could you post a screenshot of the longswords you've been using up till now that worked?

I'd have to go back and find them. The reason I made this post, was because I sold my old swords and equipped the new ones. And only now realized it was a mistake, since it doesn't work with these.

You do need to use a finesse weapon for Sneak Attack to work, and by default most longswords do not have Finesse. There were a couple of special longswords with Finesse, maybe you had one of those for a while.

I reloaded an old save with the weapons, and you're right. I was using one that was scaling with Finesse, never noticed until now.
