My idea of the best coffee grinder

My idea of the best coffee grinder would be a coffee grinder that is very durable and would not take a lot of time grinding.

It should have a blade that is really sharp and strong so that it would not be damaged after constant grinding.

I also prefer using a portable grinder to be able to take it always wherever I go.

It also has to have an option to be battery operated so I can grind even when I am in places where there are no electricity, and as a reporter, that is what usually happens to me.

I know that such a product already exists, but I have yet to find it.
