How would you interpret this card in a reading about someone's feelings for you? I wonder if they're trying to literally cut away any romantic feelings, getting them out of their head.
It really depends what deck you're using, but in RWS imagery this Knight is the only one whose horse is at a full gallop, and his sword is not being held ceremonially as the other Swords court cards hold it, but it pointed forward, like a jousting-pole, in an effort to make violent contact.
I see this Knight as the one who knows he's intelligent (after all, he's a Sword!) but is rather smug about it, and because of his belief in his intellectual superiority, he jumps in before he thinks things through.
Thus, he is quite likely to try and do the conquering-hero-rescuing-damsels-in-distress thingie even if you are NOT in distress, and actively don't want to be rescued from the situation you're in. He makes assumptions, and acts on them without thinking any further.
So he's impetuous, and tends to override the will of others. If you personally are charmed by that, then he's charming. I'm completely over men trying to be heroes to impress people, myself, but not everybody is. Some people think it's admirable. To each his (or her) own.
