4" x 1 x .40 Jasper Whetstone

4" x 1 x .40 Jasper Whetstone

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 we will send you a replacement stone in exchange, no questions asked. 

 

An excellent small sized bench stone that will last lifetimes. This stone can fit the KME guided sharpening system and others that take a 4" stone. This stone is a must have for experts or total beginner sharpeners. It will save you money big time,

because it can act like a double sided stone if you keep one side sanded and the other you allow to load up with steel you get a fast low grit stone and a fine high grit side as well. This way you don't need to add a bunch of 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. Or try a surface texture that is gritty for a sub 1000 grit sharpening feel.

 

The hardness guarantes this stone to last for many lifetimes.

When lightly slurried with a diamond plate, the pores of the stone

are opened up again like how it comes to you when you first receive it.

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 reconditioning it. 

 

  • About The Jasper Whetstones

    The Ancient Ocean Jasper is a versatile stone.

    It is very good for doing one stone honing as

    well as for refreshing edges, since it has impressive cutting speed

    when it is freshly flattened. This stone comes ready to go

    right out of the box and can bringing back a slightly dull edge

    in a short amount of time.

     

    This stone very quickly gives a mirror polish to any steel,

    at best it is in the 30k grit ball park or finer.

    Due to the stones unique geology, it also works very well as a 

    semi fast mid range stone that can reclaim dull edges with a

    bit of extra time spent sharpening.

    The reason for this is that if the jasper stone

    has a semi-coarse surface preperation it really will

    act like a fast 1k or sostone as it is starting to smooth in. 

     

    Because the stone is over all quite dense, hard

    and fine this effect

    lasts for a few sharpening sessions before your

    steel polishes the stone up again. I would

    suggest trying a worn out coarse diamond stone,

    200 grit sand paper or a a coarser slurry stone

    to reopen the cutting action on the side of your jasper

    that you are not keeping burnished.

    if you are doing chip removal in an edge it is important

    to take a minute and resurface your fast side of the

    whetstone. This will remove very minimal thickness,

    these stones will last for generations even if you lap it

    lightly before every sharpening session.

     

    When you are close to your basic edge profile,

    and the chip is gone switch to the fine side

    of your Jasper stone. This stone is special because it

    doesn't wear out, and when you slurry it with

    a worn in diamond plate it creates an incredibly

    fine and fast cutting power. The stone is almost just as fast,

    without slurry and works great with just water. 

    You don't need to soak it, or use oil.
