Unlimited nades plugin

Hello! First of all, I don't know if this should be in the scripting forum or here, just move it if I placed it wrong. Ok, to the point.

I'm looking for a plugin where everyone on the server gets unlimited nades, the best would be if they are like if you got 2 (you can throw one then throw another directly, wont need to switch to it again.) I've tried v3x's(?) plugin and ConnorMcLeod's plugins, but those are not what I'm looking for. v3x's plugin didn't really work as it should, because I couldn't give the unlimited ammo to others so they got unlimited nades, and ConnorMcLeod's didn't support nades at all.

So if anyone got a plugin like that or knows how to make such a plugin I would be really really thankful.

Thanks in advance!
