3" x 1.33" x .40 Jasper Viking 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. 


When you are out in the world and need to realign your knife edge this is the fastest and most compact stone for the job. Often our knives, axes or other tools are in need of some light honing

to bring back sharpness beyond what stropping does, for an edge. This stone makes it fast and easy for a beginner or experienced sharpener. The viking style whetstone pendant is a perfect as small hand held sharpening size. I make a filing or circular motion and it doesnt matter how

long the knife im sharpening is even though the pendant is 3" long.


This is the same super hard jasper I make all of my fine grade whetstones out of. It is impervious to dishing out from sharpening and it will cut steel fast until it loads up. One side can be kept more polished than the other to encourage it to polish steel finer. This necklace should withstand

a lifetimes worth of sharpening and it is an amazing touch up stone, for touch up style sharpening it will never dish out as you use it...


This jasper is prized for its density, fine grain and fast cutting speed. The way you dress the or let it load up with steel plays a big role in performance. Jasper will sharpen super fine, up to 30,000 grit OR semi fine like a 1000 grit stone depending on surface prep.


To keep one side cutting faster on my personal stones I lap it with a coarse girt

diamond plate (120 grit or 325). You can also use a similar approach with sand paper. 

You'll notice the more you sharpen, the more your jasper stone loads up with steel,

the more it starts to slow down. All you need to do is give it a quick lapping for 30 seconds and it will be fast again. If you slurry the stone with a diamond plate you can also use the slurry for aditional speed to the polishing action. This makes it very easy to use it as a coarse grade on one side and fine on the other.


For the finer side you can experiement with letting it load up, or slurry it / dress it now and then with fine stones or diamond plates. This natural hone doesn't need to be soaked and can be used with water, oil or slurried with a diamond plate.  This stone performs exceptionally well as a finishing stone

for straight razors. You can also sharpen dry, it doesnt need water or oil to preform.


You will never have to reflatten this stone and it cannot be worn out,

it will last a lifetime under daily use. Jasper is a robust and durable stone suitable for wearable stone carvings. The hole is drilled and the top of the stone is rounded, to accomodate the paracord nicely. 


As with all my whetstones, it comes with a lifetime lasting warranty, if you ever break it just send it back in and we will give you a replacement no questions asked.

  • About The Jasper Stone

    The Ancient Ocean Jasper is a versatile finishing 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.
