I would say give it a try, if it isn't shave ready after a pyramid on the 4/8k then the bevel may need to be re-set. This is a little tougher but I was able to reset the bevel on one of my other razors by watching Lynn's YouTube videos on his circle method.

It took a few tries but it is do able, and it also only requires the 4k/8K...you can actually set a bevel on a Norton 4K, it is quite abrasive
