Lansky Super Sapphire Hone: Ultra-Fine Ceramic Knife Sharpening Hone (2000 Grit) - S2000

I received this stone along with the deluxe diamond kit and went to work on my EDC folder. After going from extra course to fine in the deluxe kit, I opened the package for the super sapphire and immediately noticed that the stone was falling off from its plastic mount. Further inspection caused the stone to completely detach from the mount. Before going through Amazon, I contacted Lansky through their website. I received a reply within 24 hours stating that they normally require the product to be returned for QA inspection and a replacement to be sent, they waived this for me! That is a plus for me because I ordered the item with the sharpener to take advantage of free shipping, and was afraid that sending the super sapphire back would cost more than the item itself. That alone shows how they care for their customers. Any company willing to back their product like that is a good company that I certainly would do business with again, and in fact will. Their customer support truly is 5 stars in my experience.As others have noted, it seems getting that mirror finish is nearly impossible, but I may be doing it wrong here. Getting a mirror finish takes time and effort, something I havent put too much into that particular knife since I was just happy to have it shaving sharp and even happier finding out about them sending me a replacement stone. If you inspect the folder that I did, you will see "patches" of blade with a mirror finish, so I dont doubt the sapphire's ability to put on a mirror finish, I may just be using the wrong technique.

I used the complete Lansky diamond sharpening system on several neglected knives and was very pleased with the end results. The ultra fine hone delivered as promised and I could have walked away perfectly content with an extremely sharp edge if I'd stopped there. But I was curious as to how far the sapphire hone could take it. The sapphire adapts to the same system as the other hones though the ceramic isn't blue as it appears in many photos. It's white. After using the ultra fine the blade edge still showed small lacerations from the diamond stones. The sapphire pretty well eliminated all these markings, leaving a mirror-like polish and an incredibly fine edge that easily shaved the hairs off my forearm. I can't say that this final "polish" necessarily made the knife more sharp. Probably it did to some extent. But it definitely enhanced the esthetics and the end result after about 15 minutes of use was impressive. Bottom line is I think you could get by perfectly well without the sapphire hone, but if you take pride in your cutlery and you enjoy the process of working your blades, the sapphire hone is definitely worth it.

I have used my Lansky sharpening system for decades. By adding this stone and the strop, anyone can put a scary sharp, hair-popping edge on a knife because it helps them maintain the correct angle. No "one dime, two dime" guesswork here! There is something very satisfying about putting a truly sharp edge on a knife. I love my Lansky system.My stone had a little crystallization on a segment of the sharpening surface, but it doesn't seem to affect the performance. Great product!

I chose a 5 star rating because I believe it deserves it. The Lansky system is my first venture into knife sharpening. I own the Diamond sharpening system and I added this because I wanted to get a finer edge. It does deliver that for sure! For the amount of money I paid and the sharpness I am now getting on my knives I consider this addition to my Lansky System priceless!Edit:I wanted to note that the the item I received is different than pictured. My item was not a blue handle with blue stone, it was a blue handle with a white stone. But the package did say "Polishing Stone" on it. I am not listing this as a problem but for others, like me, who are a little on edge about items not as pictured.Update on performance:I cannot tell you how much I love this little guy and what it does to finish off the edge on my blades!! I had a newer knife that was losing that factory sharpness, I mean I use it a lot at work and it was still very sharp but I really enjoy a really sharp knife. I put some oil on the stone and got to work. When I was finished I put it to the paper test, for those of you who don't know what that is that is when you hold a single piece of paper and slice downwards. If the knife is sharp it will slice through the piece of paper. The sharper the knife the less burrs you will see on the paper. It was a clean cut. Very clean.I've read a couple of reviews that say this does not work, I would implore anyone and everyone who is not getting an excellent finishing edge to check your sharpening angle against the original sharpening angle. Anything different will result in no results. This is a super fine stone, and it will not re-edge your blade. Well it will, if you stroke it for over 24 hours. 10-15 on a proper angle will deliver incredible results.Update 2: 2018-09-10Still use it. Cautious of its ability to provide accurate angles on one side of sharpening. Overall disappointed.

Justo lo que necesitaba

Added this to the Lansky stable a few weeks ago and have been quite pleased. It's 2000 grit and will put a wicked sharp edge on a blade. The stone feels very smooth, almost like hard white glass. Use a very light coat of oil and clean with a soft cloth occasionally during and after use. You'll see a hint of grey on the stone and your cloth so you know that you're removing metal even if it's only a tiny bit. The end result is a mirror polish edge that is better than any factory edge (including some very high end manufacturers) I've ever seen. It takes a great deal of patience but the fact that I could now shave with my kitchen knives makes me smile.

I don't know what grit this stone is, but it's REALLY fine and it polishes an edge like nobody's business.
