Trying to find an obscure Martial Arts/Kung Fu Film where the Main Villain has a blade in his braid

Hey there guys.

Looking for this Martial Arts or Action film. I would say it was made and released anywhere between the 1970s to late 1980s. It's definitely not American Samurai or Best Of The Best 2. It had an Oriental/Asian tone to it. The movie had a hero (good guy) can't remember exactly who and the main villain (bad guy) was this very well built muscular Asian man (Chinese or Japanese) with either a fully shaved head with a long black braid with a hidden arrow tip or blade in it, or, long black hair with a hidden braid with a blade. He had a fu man chu style facial hair, or a longer goatee for his facial hair. He was wearing black leather gaunlets on his wrists and had long black pants. Pretty sure he wore a black top when he was not fighting like a sleeveless black gi and when he fought he was shirtless from memory. He had a lighter Asian skin colour and high Shang Tsung vibes from Mortal Kombat. Almost looked like Shang Tsung from the Mortal Kombat Conquest series. He would whip his hair around in a capoeira or wushu style of fighting, using the momentum of the flipping to kill the other fighters with the blade in his hair. He was the only fighter that had a weapon in the film. It was almost like it was not known by the other fighters he fought against, and he would hide it to use the blade to cheat and try and kill other fighters in the tournament.

I remember a particular scene of him at some point in the movie, entering the arena or fight area through like a prison cell door. He then turned around and closed the door behind him and then he walked along this catwalk or walkway with a menacing walk and it had like a sideview camera angle of him while walking eith some eerie music playing. He then went to go and sit down and watch some deathmatches between other fighters. When it came time for him to fight, he would use the momentum of his style and he would try and land or catch other fighters in the throat with the arrow tip or blade from his hair. He had a few fights in the film.

A few fighting scenes with the main villain I remember are:

One fight he was dancing and flipping around, just toying with his opponent. (Using the wushu or capoeira fighting style to do it). Eventually he beat his opponent to death.

Another fight I remember he started slicing a guy with his hair slowly, (like a shark preying on him bite by bite) and then either strangled the guy to death or caught him in the throat with the hair blades which killed him.

Then the final fight from memory he had in the film, was with this guy I remember was when he was against the hero (main protagonist). The hero faces him and the blade fighter's ponytail gets caught by the hero or something happens where he makes a mistake and he is then stabbed to death with his own hair blades, or, beaten to death by I'm pretty sure the main protagonist and hero.

Pretty sure it was some sort of illegal kumite tournament movie like bloodsport but a lot more gritty and violent. It had multiple different fighters with different styles. In some almost prison like environment that was torchlit and the fighters would fight on a big sandpit with a rectangular or squarish big black cage that had steel bars surrounding them. There was no escape between fights. A gong would sound between some fights and it was almost like it was illegal human cockfights. I cannot remember entirely if the fights were voluntary, they were trying to win something like a prize or if they were all being held against their will, but they had to fight in order to advance or survive. The other fighters I believe were being held behind steel bars or cells and watching the fights. Almost like Bloodfist 2 in a way. I definitely think the film was more 70s or even 80s. The movie was very violent and very brutal. From memory, it was well shot to. It was most likely a B Grade film though and it had that Asian martial arts feel to it.

Thank you in advance guys.
