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. 
 
I’ve come up with a new standard size of Jasper sharpening stone for the website! 3” x 1.25” x .30”
This size has been carefully designed and crafted to be the ultimate budget friendly whetstone, that you’ll want to take everywhere in your pocket.
Colorado Jasper stones have a few specific properties that save you a ton of pain and trouble, when you are sharpening.
Jasper Is an extremely dense and impact resistant stone, that is harder than any steel. It comes lapped flat on both sides and ready for lifetimes of use. And yes this stone performs very well sharpening super steels, it is just a little slow going but you will get a very highly refined edge!
Everyone knows that with all man made sharpening stones you are wearing your stone away every sharpening session...!
SO
If you are sharpening carbon steel you might be able to get away with not flattening softer sharpening stone for a couple of sessions, but if you are sharpening harder steel you will notice that immediately most stones begins to dish out as you are working on the edge. 90% of the sharpening stones on the market have this issue, but not jasper!
Jasper has microcrystalline structure plus high density which makes it impervious to gouging, and very hard to break by dropping.
This size comes in at
3” x 1.25” x .30” Ancient Ocean Jasper, pocket stones. Looking at $37.50 shipped in the USA for these lifetime lasting Whetstones.
Also, as a bonus these come dual grit! One side is coarse, 1000 grit sharpening feel, the other side polishes up to 30,000 grit.
This takes me a lot of extra time to do but it’s well worth the results your stone gives. If you are working on a knife that needs a huge chip removed then you may find this jasper too slow compared to a diamond whetstone, but if you are just working with a dull knife you can fix it rapidly, getting it back to razor sharp in just a few minutes.
