I'm glad I got this stone. I have Chosera stones in other grits but this was an in-betweener grit that I needed. It cuts very nicely and fast. Saving me a lot of time before I get to the 800 grit stone.

Si quieres una piedra que afile con pocas pasadas un cuchillo estándar de cocina está es de las mejores que he tenido.Si es un cuchillo de acero duro, quizás compraría una de grano 220 y otra de 800 para afinar la terminacio .Pero para el 99 % de los cuchillos, con 20 pasadas por cada cara, el cuchillo corta mucho.

The best stone for knives ever made. It's the best value, I would get an 800 grit too but yeah, you can't beat the value or the quality. After this point you can spend more money sure but the grind patterns will marginally improve. I would not use this to Sharpen steals like S90V, Use diamond plates for that and don't press down too hard on the diamond, you will dislodge them. For the wet stone, please use this with a metal over the sink holder. This way you can run water over the wet stone which helps keep it clean, gunk-free and you avoid the long soak times. Remember to get a leveling stone, A cheap one will do, $15 bucks. If you need to know more just leave a review asking for help or a guide and i will answer your questions. This is the best brand. Also learning to hit the same angle ever time is the most important factor of all. It's hard and takes practice but there are good guides you can use and youtube videos to help with that. But yeah Again this is the best brand in the world. You can look at the grind patterns on the knives under an electron microscope to confirm how good this brand is. Scientist have done this and the grind is amazing some of the best out there. This rivals $400 stones!

Great price and services from Amazon.It took me many years to cross over to Amazon after being an avid eBay shopper and was pleasantly surprised as to the service and the way I was treated.Amazon kept me briefed during the entire process and delivery. Same day delivery was awesome.Stone did not disappoint one bit when I got to to use it. Great Range of stones and it cuts the metal very, very well.Most disappointing thing was I was at home when the delivery guy came and the front door was open. He didn't even knock as he was to busy on the phone talking to a friend and he just threw the parcel onto the front step and just walked off. Being a Whetstone it was quite upsetting to see and hear my goods being tossed around that way.After such a great experience with the purchase and Amazon service the end was marred by the driver and his attitude. Hope he wakes up and pulls his socks up5 Stars for the Great Quality Stone and Amazon Service but NO Stars for the driver

I've a lot of low grid stones and I always use the Chosera 400. And the fact that it is an splash and go, I can use it witha few knives until the soaking stones are ready.

Estoy esperando la última piedra que ordené ya tengo grano 400, 600, 1000 y 5000 me falta por recibir la piedra grano 3000, acabo de usar todas las piedras para afilar un Muela Podenquero de doble filo que me llevo al monte cuando vamos de cacería del Wild Boar en el sur de Texas y les aseguro que quedó como un bisturí, también afile un Bowie Cudeman e igualmente otro bisturí, afile por diversión un PUKKO Finlandés que venía con mucho filo y me impresionó que en un medidor de filos que tiene un amigo fabricante de cuchillos marco 120 o sea mejor que una navaja barbera y también pulí el filo de un Fallkniven S1 de acero Lam Coos y es otro bisturí, si tienes filos de calidad no escatimes en herramientas de afilado a la larga te salen más baratas que comprar piedras corrientes, de hecho tengo 6 Katanas que únicamente pulo con la piedra 5,000 de Chosera y después uso aceite de Camelia para proteger el acero, todo lo encuentras en Amazon a buen precio, se las recomiendo ampliamente

These are Middle of the Line bench stones but perform exceeding well in practice. I bought the set of three and except for my Spyderco Stones and my Shapton Glass Stones this set is actually all the hobbyist would need! They are easy to use (no soaking for minutes in the beginning) but splash a little water on them and you're good to go. I am quite happy to have them in my collection of bench stones.(I am going to write the same review for all three grits of this stone, and heartily suggest purchasing all three which will give you the full range that you need - I've rated each of the three the same).

If you stumbled upon this stone and you're unsure if it's an authentic chosera stone, don't fret, it's the real deal! I wasn't sure why it is listed as "super ceramic" but according to a japanese youtuber by the name of virtuovice, chosera means super ceramic, so there's absolutely nothing to worry about.Everything about this stone is amazing. I was taken back by how beautiful the overall packaging and presentation is. I own both the new naniwa pro and this chosera. This stone preforms head and neck above the pro, so if you aren't sure which one to get, get this one. It comes in a very colorful and well made box with a #600 dressing stone, the pro is 5mm skinnier and does not include any of the fore-mentioned goodies, it's actually quite plain and cheap looking, not to mention the feel of the new stones are nothing to write home about. Just to be clear I ordered my stone from amazon and it arrived in excellent packaging without any defects, it's a sure thing.IMHO this is the stone you should begin with, learning to repair and re-profile is an indispensable skill. If you wondering what stone to move to next, hands down the #800 chosera which also sold here on amazon.

The Chosera line of stones are my favorite. I sharpen knives as a side job and these are my go to stones with expensive kitchen knives or knives with super steels or expensive knives in general that I wish to give the best treatment. The stones are splash and go, DO NOT SOAK, and are extremely hard and slow wearing while cutting metal very quickly. Smoothest tactile feel of any water stone I've ever used. Just an absolute joy to use. Like ever other stone in this line, it polishes above it's grit level but still cuts as fast as the stated grit. In a progression, I usually use this as the first stone for very dull blades or blades that need a chip repaired or need to be reprofiled, etc before stepping up to a 1000. I've never found the need to start with a coarser diamond plate either, this stone makes quick work of even the hardest metals with large carbides. This is the older version that is 25mm thick and comes with an attached base and nagura (which I never use but, I know some people like them). The newer stones are branded "Naniwa Professional" they are 5mm thinner and come without the base for the same price but are supposedly harder and slower wearing but I have not noticed any performance differences between the two versions so, definitely go with the older Chosera version as long as they're available.
