4" x 1 x .40 Jasper Viking Whetstone Pendant
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 about the best stone you can get.
When you need to do some fast honing to bring back a razor like edge
on your daily carry items, this stone preforms faster and sharpens finer than what you can accomplish with just stropping your edge on leather.
This viking style whetstone pendant is a comfortable hand held size.
You can also lay your knife or axe or whatever you are sharpening flat,
and use this stone like a metal file, while holding the lanyard end.
This is the same super hard jasper I make all of my
whetstones out of. It is super resistant to dishing out
and it will cut steel fast until it loads up.
If you let one side load, and lap the other occasionally you get a dual grit stone.
You'll notice the more it loads up with steel, the finer the jasper polishes and
the more it starts to slow down in cutting speed. All you need to do is
give it a quick lapping for 30 seconds and it will be fast again, this barely removes any thickness of the stone and it will last for many generations even used daily.
For the finer side of your stone 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.
This jasper whetstone is as fine as 30k grit yet it also cuts steel
very quickly if sanded to a coarser texture. You will notice it removes steel
and refines your edge every sharpening stroke.
When slurried with a diamond plate,
the stone polishes extra fast, but that's not required because
it also is exceptionally quick when freshly dressed.
You will never have to reflatten this stone and it cannot be worn out,
it will last a lifetime under daily use.
About The Jasper Whetstones
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.
