I'm puzzled,what is the difference between sharpen and unsharp mask?
I think, and i stress, think, that unsharp mask you can control more and with sharpen its just the bulk standard sharpen function.

Sharpen was the first tool that Photoshop had, an improvement was Unsharp Mask which allowed slightly more control. Currently "Smart sharpen" is the tool of choice as many tutorials now advocate - e.g. http://www.luminous-landscape.com/tutorials/smart_sharp.shtml

unsharp mask basically uses a softened version of the image as a mask to the original, thereby cancelling out the blurriness to some extent. Worth a search on Wikipedia on the subject :)
