The Suehiro Rika 3K Ouga is a standout product from the same renowned line as the Rika 5K. This exceptional middle-grit stone, featuring a striking yellow color, is one of our top recommendations for achieving a fine finish on kitchen knives.
The name "Ouga" translates to "The King", which is fitting for a stone of such high quality. It serves as an excellent finishing stone, particularly for those seeking a balance between a toothy edge and a refined finish. Pairing this stone with a lower or medium grit stone, such as a 1K or 800 grit, allows you to create an edge that effortlessly slices through tomatoes or peppers while maintaining long-lasting sharpness.
The stone measures 205 x 73 x 27 mm, providing ample surface area for a comfortable and efficient sharpening experience.

Far Too Coarse, January 24, 2026I have been a woodworker for almost 50 years. I have a long experiences with sharpening edge tools. I have fine oil stones dating from the 1970s, and a comprehensive collection of Japanese waterstones. For years now, I have been employing the waterstones exclusively. I have used most brands over the years, Bester, Shapton, King, Naniwa, etc. . I am giving this preamble not to bore you, but to lend some credibility to what I have to say. My hope is to spare others form wasting their money on this stone. So here goes - This stone is rated as a #3000. In fact it is more like a #1500 . It leaves scratches so deep that you have to drop back down to a #2000 to get rid of them. This #3000 is significantly more coarse that any #2000 that I have ever employed. It is a coarse #1500 stone being palmed off by the manufacturer as a #3000 stone. As the coarse cutting stone that it is, it should by no means be sold as a #3000 stone. It is of no use for the intended purpose of sharpening in the #3000 range. Knives To Go is a fine and reputable company. They would be doing their customers a service if they dropped this brand from their line up.
Like this stone a lot39 people found this review helpful
Very nice middle grit stone. I find it to be a bit harder than the Rika 5k. Still has very good feel and feedback. It's not quite as fine as some other 3k stones I've used, kind of like the Rika 5k seems a little coarser than other 5k stones I've used. It feels a lot like a finer Cerax 700 to me if you're familiar with that stone. No complaints at all, it's a very nice soaking stone you don't often see discussed. I often won't take my stainless kitchen and hunting knives past this stone, it refines the edge well but leaves enough tooth for good slicing aggression
Great mid level stone before polishing34 people found this review helpful
Great mid level stone before polishing...great feedback like all the suehiro rikas...pretty hard so it will last a good while creatse mud at an average rate not to fast not to slow....also does a nice job with single bevels ( if you are doing a kasumi finish)....all in all great stone... suehiro rika line is great espcially if you like stone,s that soak in order to sharpen both single and double bevel knives
Very nice intermediate stone!31 people found this review helpful
I very much like the feel of this stone. It is on the soft side, and makes a decent amount of mud. I find that it cuts fast, but unfortunately also tends to blind very fast; I usually have to lap the stone often during sharpening with it. Even though it has a soft, silky feel, it really doesn't wear too fast. In my hands, most of the wear is due to removing the surface due to the blinding. Overall, pretty much the best feeling stone I have used in this grit range. On balance, a really nice stone!
