I am at the very edge, a tiny helping hint. I am a handful of pennies given to one who serves. Five of me sit upon each hand.

I can run but cannot walk. Without me, your food tastes bland.

I can start a fire, Or flash from a wire. If you want to make your mark, You'll need a big idea, inspired by a blank. What am I?

I can be many things, great or small. I can even be non-corporeal. I'm not heavy, on the contrary. The dark I scare away, and after too many drinks your head will feel this way

If you climb over me to obtain something that wasn’t yours, you will need me to unload your ill-gotten asset.
