Another, more flexible approach, that will work with grayscale:

1. Apply the sharpening to a duplicate layer.

2. Reduce any overall over sharpening by lowering the layer opacity.

3. Add a layer mask, with "reveal all'.

4. Paint black on the layer mask to remove some sharpening in a particular area, with an 
opacity for your Wacom brush set to allow reasonable control. Try 25% as a start.

4a. Or, paint some shade of gray on the layer mask with your mouse.

5. Don't like it? Delete the layer mask and try again. Or delete the duplicate layer and try 
again.

Hope that helps.
