The Norton flattening stone arrived today and it removed whatever the razor was hitting before. The prep stone makes a great slurry. Now, I'm a happy camper again.

Thanks to all who pointed me in the right direction. I had originally ordered the Norton 4K/8K from Executive Shaving in the UK and I'm still somewhat surprised that they would sell such a product without any mention that it needs to be lapped or that such things as a flattening stone and prep stone exist. If it wasn't for all the help and advice I've received here, and especially however it was that I got pointed to The Perfect Edge, I'd be in a hell of mess.
