- I watched a chinese movie in the early 90’s. It had a lady who sometimes put her ponytail in her mouth to gain extra strength when fighting. But I cant remember the title.
- A movie in which a mysterious driver had a knife on his car tyres and was causing accidents by piercing other drivers with the knife from his tyres.
“Death Race”(2008)?
Thats my guess for the 2nd one
Horror Hospital (1972)
Grease (1978)
These movies also had a knife or blade in a wheel.
