6 PCS Diamond Knife Sharpening Stones Set, Diamond Plates Kit for XARILK type Sharpeners System, 180# 400# 800# 1500# 2000# 3000# Grit

Work very well. I'm able to get a razor sharp edge on any knife that has good steel. Some blades take longer than others depending on the original angle of the edge.

I like these so far, the aluminum backing is a far better platform. The stones seem to cut well, though I've not used them a whole lot yet. I do believe they cut maybe a little better, than the original diamond stones that came with the Zarilk angle guided sharpener. Time will tell if these stones wear any better than the original ones, as those seem to wear out fairly fast. I think the product works well, for the price I paid. I've yet to purchase the higher priced stones, to make a fair judgment in comparison.

The kit that adds 6 more diamo d plate are not the same quality as one come withrhe sharpener. Rhey are Not aluminum backed. They are plastic backed and bit flimsy.The sharpener works well. I reco.me d the sharpener, but do not buy the 6 additional diamond inserts.Only other company is that the hole where the sharpener rod go through get loosened often if you use even a bit of force. I couldnot tighten that down enough to keep that in place.

Wow, these are great stones... solid bases and the diamonds on mine were nice and flat without imperfections. Almost no variation in thickness so I didn't need to reset my angle when switching stones. The aluminum bases needed a bit of dehorning cause there were some pretty sharp edges but other than that, I was so impressed I immediately bought another set for when these finally die. I believe these will "break in" beautifully as they are very sharp out of the box. I only wish there were more grit choices in this style. I have searched quite a bit on Amazon but can only find the ones on plastic bases. Out of the box these seem much more coarse than the grit would suggest, hence the break in, but the grind was very even without much scratch variation. Brand new the 240 cuts like a 120 and the 1000 cuts probably about like a 400-600 but develops the burr very quickly and I use regular stones to finish anyway. Due to their origins, there may be QC issues so if you get a bad set, exchange them because the good ones I can tell you are phenomenal for the price.

Good quality metal back and these are honeycomb diamond stones wasn't expecting that but definitely good quality

Kudos to Xarilk for upgrading the sharpening stones that come with the Gen 3 knife sharpening system to have a metal backing to prevent flexing when mounted. HOWEVER, the stones that come in this "add-on" set have not been upgraded and suffer from the flexing problem. This was a combo deal on Amazon (gen 3 knife sharpening system and extra stones) you would think that they all would have been of the same quality.*UPDATE*After contacting Xarilk customer support, they sent out the newer metal backed "add-on" stones - no charge. Also, they pointed to a more current bundle that has all metal backed stones (search for B0DDXMLK2X, it should be the first item listed).They were very responsive (messaging on weekends and way past normal office hours). Changing my rating from 1 to a 5. Thanks for the great knife sharpening system and the awesome customer support!

These aren't the highest quality, most durable stones. But they work OK. The alternative is paying $30-50 per stone. (Update 04-28-25: When Xarilk read my review, they reached out to me and offered a full refund, which was very generous. I declined the refund as the stones are certainly useable - they're just not super high quality. I highly recommend as "starter" stones.)

Nice set of diamond sharpeners.
