Cumi Carborundum CSSC109 Silicone Carbide Combination Stone, 150 X 50 X 25 Millimeter, Black

AMAZING!!!! AMAZING!!!! AMAZING!!!!! AMAZING!!! (Tips included) Guys dont give a second thought, just go for it! I had purchased a useless Bergner knife set Bergner Knife Set, 8-Pieces which came with very blunt knives. So I had to but another Rena Germany Chef's knife Rena Germany - Knife - Chef'S Knives - Black Color - Stainless Steel - 210 Mm from amazon to go about my work. This knife was sharp as hell. Now my stone arrived yesterday and I honed my Bergner knives with it and trust me, they are as sharp as the Rena Germany knife, actually even sharper. It's a must have for your kitchen. It's surprising how low priced it is. Before using this stone, I suggest you watch some videos on Youtube about using combination stones. Tips 1. before sharpening immerse the stone in water and keep it that way until the bubbles stop coming out of stone 2. If you choose to use oil once,(for lubricating) always use oil and same with water. DO NOT SWITCH between oil and water. 3. This stone comes with a double grit. For coarse honing (if your knife is too blunt), use the dark green surface. For getting the fine edge use the lighter green surface where the logo is printed. 4.The packet recommends you to keep a 30° angle, but i personally prefer keeping a 20° to 25° angle for European style knives. Feel free to ask me about anything related to using this amazing stone. Happy Coocking!!! :)

I wanted a sharpening stone for mom's kitchen knives and an array of Swiss Knives and Pocket Multi Tool's I have collected over the years. I always used to go in shops inquiring for this but used to return empty handed due to unbranded and suspicious stuff. I came across this product on Amazon and did some research on it. It is from a very popular brand down south named Cumi. I placed and order for it and received the delivery on time with nice packaging. From my usage I have found that it sharpens all kinds of knives in a jiffy and one doesn't has to put much effort while sharpening knives. I am very happy and satisfied using this product. Thank you Amazon.

Excellent item.

It is an Ok Ok product. Does an Ok job in sharping the blades / Knife. It can be given or designed with a grip since it keeps moving. And the sharpness is not that great. But yeah can manage. I just received it today. I will use it for a while and update the usage too.

I recently revived my hobby for knives and thought of starting by sharpening the kitchen knives using this stone. It brought life back into the knives. Dimensions are very good making it easy to use. The course side really shaves off the metal from the beavel of the blade restoring the damaged blade straight and the fine grit really sharpens the knife to a fine finish. Sharp enough to start enjoying cutting vegetables. If you want to sharpen a camping knife, I suggest to add a 1000 grit to the sharpening followed by a strop. You can't expect razor sharpness but you will sure love sharpening with this stone at a pretty low cost!!!

Good product at this price range. But not suited for SS knives.

I had couple of knives which was blunt and was not able to cut through anything. I was rather skeptical when I bought this and tried to sharpen the blunt knives. The first time I tried this I did not get any result and the knives stayed blunt. I watched some YouTube videos on sharpening and slowly learnt how to do this. Indeed after doing it right the knives sliced through everything smooth as a butter. This stone needs to be soaked in water for couple of hours before it should be used and the sharpening angle of the knives should be precise to get the best out of it..Overall I am very happy with this product as it has given life to old knives which otherwise I would have thrown it off.

Does what's expected.

Worth it
