Lansky Super Sapphire Hone

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 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.

Like others have said, watch out. Mine came with a slightly concave stone. It's still usable and while it doesn't give me that nice polished appearance, it still produces a very sharp edge. I can at least shave hairs off my hand with the edge it produces. All the other stones I have in that kit are flat. Maybe I can fix it by progressively sanding it down? -- 7-1-2018 Update -- I flattened the stone on a cheap Harbor Freight diamond hone from their 3 piece set with plenty of water. After about a while, I checked it with a small 3" square to make sure it was flat. After the initial flattening, I moved to water soaked 2000 grit sandpaper on a small sheet of glass. All in all, it took around an hour or so to get the stone back to what it was originally. The polishing the stone does now if far more uniform now that the stone isn't concave. -- Afterthought -- I wonder how difficult it would be to make these using 1/2" aluminum extrusions and lapping film.

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.

Lansky bills the Super Sapphire as the ultimate finishing stone for the Lansky system and I'm not going to disagree. I find that the super sapphire has a bit of a granular feel, with more bite than the pink fine or white ultra fine stones. It feels like it removes more metal than either of those, I get a robust burr pretty quickly - but the edge produced is blamelessly sharp. I've had it for a month now and always use it after the pink fine stone and marvel at how well and quickly it raises a burr compared to the pink or white stones. I find that a bit mystifying given that the grit is finer. Maybe the super sapphire is finer grit but softer? In any case it's an awesome finishing stone. My knives have a razor-like finish.

Works with my other Lansky accessories.

Ok, I received this stone today... The thing that first struck me was that the stone is a white color instead of being purple as shown in the images. I compared it with the Ultra fine stone (white stone in a yellow holder) that I received at the same time, and they feel pretty much the same. On closer inspection, the working surface has a recessed area about 2/3 of the way up the stone, where it's not flush with the rest of the surface. It's a pretty big defect for a super-fine polishing surface. I've contacted Lansky using their website, and will update this comment based on their response. Note that I've been using a Lansky sharpening system for about 25 years, and am a big fan. Don't let this negative review dissuade you from trying the Lansky system. Update: I contacted Lansky, and they sent me a replacement stone. The replacement stone has a flat working surface, which is a big improvement. Unfortunately, the edges were jagged. This isn't something that would affect the use of the stone, but it is unsightly. I used the diamond-fine stone to smooth the edges at a 45 degree angle, and got rid of the jagged edges. Note that the replacement again was a white stone, not the purple stone that's shown in the images and on the packaging. I used the new stone today, and it seems to have a more coarse finish than the ultra-fine white stone. This despite the sapphire stone being advertised as 2000 grit and the ultra-fine stone being advertised as 1000 grit. Oh well, either one works well for putting a final finish on the edge. Upgrading to 5 stars for Katherine in the Lansky customer service department standing behind their product.

These have given some really ordinary knives a bit of an extraordinary keenness. However, I found that longer knives are better to do in two parts. The angles get smaller the further the hones are away from the jig that holds the knife. It is better to keep the angle similar throughout the process. Hence, better to break the job into parts. There are enough rods to set all the required hones up first, then get into the task of sharpening. A good product.

J'ai acheté cette pierre pour compléter mon kit Lansky. Elle est de très bonne qualité et permet de fignoler le travail à l’extrême. Son grain, pour moi, correspond à quelque chose entre le grain 1500 et le grain 2000. Rien à dire , bon matériel mais pas forcément indispensable ... Si vous avez trouvé ce commentaire utile ... Faites un petit clic sur le oui en dessous :)

Awesome quality and really puts that razor edge on knives that have been sharpened up to 1000 grit. Highly recommended

Avendo acquistato un set di coti della Lansky deluxe fornito di cinque pietre di varia granatura mancava quest ultima, certo non indispensabile ai fini di ottenere una buona affilatura ma indispensabile per ultima rifinitura.Dona un ottima aspetto alle lame rendendole perfette.Davvero un buon prodotto.Ultimo passo per perfezionare l aspetto delle lame. Consigliato.

Tardó un poco en llegar pero es una muy buena piedra, puedes darle un acabado pulido al filo de tus cuchillos y navajas, no lo dice en la descripción de Amazon, pero es de grano 2000, recuerda que debes contar ya con el kit de afilado de Lansky
