Elaine, mine is the original basic long one. I have a few, some with a black handle, some without.
I use it for fruit zest and cheese, but the grate is very fine. That's why I asked what result you were looking for...this is pretty fine.
And they do dull out eventually.
I've even used mine to scrap off burnt edges on toast and bread and to fine-tune the edges on the Gingerbread House.
