Hold up there. Dont kick him or anything like that, you may end up getting even more hurt than before. If he has a knife, it is a concealed weapon and you can report him to your principal or even a police dept.
Don't fight back unless you absolutely have to butif he attacks first, then yes, you can count it as defence... PLEASE don't unless it's serious and he's actually attacking you or else it could get far worse.
DO NOT kill him! For God's sake guys, don't encourage very violent actions (my first post included,

) including death or even like other grusome things.

You can always bring a slegdehammer to school and pop him in the knee like the mob does...and hes shorter then me If I was there I probably kick him in the a** and shove him in a garbage can and throw the can down the closest hill oh and maybe target practice with bottle rockets like spike dont ask what happened then It invovled the court system and something else...
this is very serious matter and it should be talked about with other adults. But, if this gets you in more danger, do it anonymusly.
