the difference between unsharp and sharpen

So now that I have all of your opinions on Sharpen, I was curious, what really is the difference between Sharpen and Unsharp. I am under the understanding that Unsharp is also for sharpening images, but I don't really get it, why 2 plugins? Whats the deal?
Thanks again everyone.

I have the same thing in PhotoPaint dand have wondered about that seeming contradiction/redundancy too. I just use whatever works best,

But it is also one of those little "Hmmm..." life questions :o)

Unsharp-masking is a more sophisticated process for sharpening images.

The 'unsharp' comes from the initial step which is a gaussian blur.
