I know this is such a stupid attempt but I was tempted when I saw a challenge on a YouTube comment. If you want to try it for your self:
Must use Knife only.
Grenades can be used.
Can kick.
I told my friend that I was going to do this and he added another thing to the challenge. He said that I must get 30000 and above. I'm very young and I'm going to prove this.
I died purposely in the end because I didn't want to use too much space and I killed myself after realizing I reached 30k+.
