Quick question for you hone experts out there. I recently purchased a norton flattening stone for my 4k/8k. Problem is after I flatten the 4k side it no longer cuts....I know this sounds bizarre but I've used this stone for 2 years with no problems. The 4k stone is abrasive, but it takes no metal off the burr... any suggestions? FYI, the 8k seems to be fine...
BTW, I used to use sandpaper until recently when i glazed my stone with a low quality brand and decided to switch to the flattener.
