Also, it looks like the querent is looking for a mechanical explaination of how two system feature works, and you first suggest a different strategy
(which is not the one he has problems understanding, he is not looking for advice on how to use the character, he is trying to understand the rules), then you dscuss the defensive utility of the sword (and not by the rules, but introducing a "probably" and a "I would"), lastly another "I would do this". Basically, you didn't ansswer the question.
