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. 
 
This Viking Whetstone Pendant is carved in carefully selected
Nephrite jade. It is slightly more dense than the jasper stones I carry and far more robust. Jade is ultra hard, cannot be gouged by steel and will resist serious impact like a hammer blow or dropping it on concrete.
 
Small whetstones often were worn as pendants by many northern peoples, including Vikings. This Jade whetstone is a replicant of softer slate whetstone pendants found in archaeological digs in York, England, but similar pendants have been found in Gotland, Norway, Kalåstad, and Birka. 
 
I find Jade is a superior honing stone to the slate or jasper used historically. Jade is extremely strong and has a very fine grain. Thus it is excellent for final honing and also stronger than those aforementioned stones. However there is a technique to use this stone for rough grit sharpening, as well.
 
This Viking Pendant comes highly polished on all surfaces.  If you would like to increase the cutting grit for more rapid steel removal when sharpening, you can take the polish down on the back of the pendant or the sides with 200 or 400 grit sand paper, just rub it on a flat surface for about 30 seconds to a minute. This lets your stone cut at the grit that your surface is prepared at. For example these come polished to 30,000 grit and will easily give steel a mirror polish. If you want your stone not polished or sanded a specific way select that in the options chart or leave me a note in your order.
 
This ability to change up the surface lets you decide if you don’t mind the stone being fully polished, or not. The back surface can be used to sharpen coarsely if you like. A less polished surface on jade is fantastic as a rough dressing stone for initial sharpening or refreshing a dulled blade. 
 
Jade is way harder than steel, so you never have to worry about gouging your necklace and it will never wear out in multiple lifetimes. Your great grand children will inherit this.
 
Jade does quick work of removing steel. and finely re-aligning an edge that's slightly dull. Or dress your jade with coarse grit for it to sharpen much faster. If it's lapped rough and not polished it can still be made to look shiney by oiling it. 
 
This is a lifetime lasting sharpening stone, it cannot dish out and it cannot be gouged. It also can take up to a 6 foot drop on concrete. 
 
When fully polished or loaded up the stone will continue to sharpen so
it's not critical to lap it. Sharpen wet or dry, water or oil. Cheers and check out the training videos on the home page for specific tutorials on how to use these stones
