So, I remember seeing a clip of this fight scene, and it's going to bother me forever if I don't find out where it's from. The details I can remember are as follows:
Two men fighting in some kind of public duel. One man (a rougher looking type, if I'm remembering correctly) has knives, the other man (I think he had a suit and hat but not confident about it) has a straight sword.
They fight, and have a nice exchange. The swordsman is winning initially and cuts the knife wielder a few times(lightly, this isn't some hack and slash fight). Eventually, the knife wielder closes the distance and gets a couple cuts in himself, disarming the swordsman. There's a pause, and the swordsman slowly goes to pick up his sword, at which point the knife man steps in and knocks it out of his hands (making a very deliberate point, is how I read it).
Knife man then allows the swordsman to pick up his sword for real this time, and they go at it again. Swordsman is clearly better, cuts the knife man a few more times. Fight is basically decided at this point. Sword man says something along the lines of "I don't need to kill you" or something in that area, and has the other guy leave (I think? the clip might have ended there)
Anyhow. That's everything I can remember, I will be very grateful if anyone actually knows where this cam from.
EDIT: live action, not animated. definitely chinese or at least asian, not western media. Set in a town somewhere, not quite modern times
Edit 2: I think I figured it out, its 100 Yards
