Sharpening>type in Norton> look for the numbers I give.
Norton 630
India
·Combination coarse/fine stone
·Measures 3" x 1-1/2" x 1/2".
Same stone, just smaller. This is the stone I have used from Canada to Jamaica.
I grew up with these stones, literally. I was born in '55, and these stones hav always been in my life. These were given to me at birth.
This one stone, will sharpen anything, and has for me.
I use these stone dry no oil, no water.
Seriously, this Norton India coarse/fine is the only stone one really needs.
If were to only have one oil stone, this is the stone to have.
That said, If you can find the Norton Extra fine, that is a nice find.

Case made a Moonstone, this is a very unique stone, and I wish I had mine.
I have/had special sharpening needs.
Surgical black was for gold testing and assaying, and sharpening surgical and precison instruments.
Moonstone was used for some similar applications.
Back in the day, we had access to Ark stones - free.
Even so, the only stones we really used were the Norton, Case Stones, and some hand picked stones from the Quarries and finishers out of Hot Springs.
Our people went to Hot Springs to hand select the hard black, and other needs.
I've watched hand engravers, doing intricate work on guns, gold, reverse engraving on signet rings with family crests...
I've watched a person do brightcut work with dias, pave' work with diamonds and set a stone worth $250,000.
That carbon steel, tool steel tool, had better be sharp!
One little slip and things are de-valued right fast!
I know what tools they used, never stainless, and always a Norton Stone was the primary stone.
Might explain why I don't care for stainless and goopy sharpening systems...
