Could you imagine the threads if everyone could afford 30k Shaptons ?
" I sharpened my razor with the 30k Shapton and..... ( insert negative results here ) "
And the replies would be. "Works just fine on xyz razors."
For Kuromaku Shapton says 2k , 8k, 30k for razors. Would that progression work ? Of course, if you know what you're doing.
I know from experience the Kuromaku 8k will remove small chips & set a bevel but like me you might be scratching your head as to why it took you 2 hours. The 8k & 2k are both green. Best to label each box & stone clearly:roflmao
I also know that the 320 ,1k & 1.5k are great for restoration purposes yet Shapton don't say that.
I tend to agree with Steve that Shapton's recommendations are for "a new razor that’s properly made and ground and does not need corrective honing."
