This sharpening stone can be an all in one whetstone solution! When the surface texture is 
prepaired semi coarse to coarse it sharpens at a sub 1000 Grit level, flip your stone over and the finer side can polish up to 30,000 grit or a mirror level of finish. As the stone loads with steel it gets finer and finer, we recommend that you scuff up the surface on occasion with a fine or rough diamond plate (120 or 600 grit) to acheive the dual grit surface effect. The stone can quickly make the transition from the bevel setting grit to fine grit finishing. This sharpening stone is ultra hard, it cannot be gouged into with steel and it never needs to be flattened. If you mess up your sharpening stroke angle you will not gouge into it.
 
This sharpening stone will last multiple lifetimes under regular use. This whetstone also comes with a lifetime lasting warranty, should you ever break it will will send you a replacement stone in exchange, no questions asked. 
 
An excellent sized stone that will last lifetimes.
This stone fit's the Grit-o-matic guided sharpening system.
 
This stone is a must have for experts or total
beginner sharpeners. It will save you money big time,
on needing to add  other stones to your sharpening kit.
Mother nature knocked it out of the park
with this incredible geological combination.
This stone is incredibly hard, fine and fast cutting.
It will never require the surface to be reflattened because
it simply doesnt dish out, or gouge.
 
The surface of this rock burnishes finely
when you sharpen on it. You will see it eat a streak of metal 
each sharpening stroke.
 
The hardness guarantes this stone to last for many lifetimes,
and also allows the back side of the stone to be coarsely prepped
and it can be used like a grinding stone / metal file! 
When the stone eats metal it slows down, so you can dress the surface
quite quickly, within 30 seconds using coarse or finer sand paper.
When lightly slurried with a worn in diamond plate, the pores of the stone
are opened up again, yet it also gives you an incredibly fine and fast slurry.
 
With use the stone starts to get loaded up with metal from previous
honing sessions, getting finer and finer.
I recommend you add a fine or worn out diamond plate to your kit
to be able to do a full sharpening session with just this one stone,
by slurrying it and conditioning it. or dress the surface with
sand paper or slurry stones when it loads with steel.
