The blur / sharpen is very old, I can not remember when I last used it. It uses a mathematical procedure called convolve and if you look that up https://en.wikipedia.org/wiki/Kernel_(image_processing) you can see that sharpen is not the reverse of blur.
This tool does not have an layer effect (fx) ability but you can use the other blur and sharpen filters and constrain the area using a layer mask.
