Saphire Stone
This seems to be a good product. You must be careful using this as it will raise a burr. I use it very lightly with the same amount of passes on each side of a blade and it works. I test the blade sharpness by shaving arm hairs and my blades were like razors. I've never had blades grab and cut hair the way the newly sharpened blades dousing this.
Another test is to lay the blade flat on the back of your head with the edge pointing downward. Slowly slide the blade down and at the same time turn in the blade so the edge faces your head. A sharp blade will grab your hair. I've tried this and the blades REALLY grab after using this stone.
I try to put the best edge I can on all my knives and on the knives of friends and family that ask me. This thing makes me nervous to even give them back in fear they may cut themselves.

Incredibily super sharp
If you use a Lansky sharpening system and are contemplating buying this stone - go and get it right away !! It really is as good as claimed.
I've been using it for 4 months now and this Sapphire Hone is superb. It is 2000 grit, which is by far the finest grit available apart from some exotic Japanese polishing Waterstones
For Lansky users - bring your edge up to sharp, using the Medium then fine, then ultra fine hone (Lansky yellow 1000).
Then finish off with the SAPPHIRE. The sapphire is extremely fine, but is still capable of raising a burr. So I have found that the finishing strokes need to be very, very gentle. Keep stroking, alternating one side to the other until there is no burr left. You will then have a superb razor edge
The above description is how I use the Sapphire to put the very sharpest ultimate finish on my smaller (about 4") Global kitchen knives.
If only Lansky could produce a full size Sapphire, sharpening stone for bigger knives, they would have a world beater.
The Sapphire gives as fine and polished edge as the 6000 grit Waterstone that I currently use for my bigger Global knives.(5 1/2" or longer)
How do you test for sharpness?
The genuine Samurai Sharpness Test: To test for sharpness, lay the blade flat against the back of your head, blade edge down. Then GENTLY and CAREFULLY tilt the blade outwards so that the cutting edge is against your hair. VERY gently start to move the cutting edge downwards. With a really sharp edge, you will feel the edge "bite" into you hair immediately. DON'T CUT YOUR HAIR !! Once you feel the edge biting, remove the knife. If you did not feel the edge really grabbing your hair, the edge is not razor sharp.
After using your knife You can keep the edge sharp by using a Kyocera Ceramic steel CSM-18 with very gentle stoking.
Happy sharpening!!
