NANIWA COMBI Ceramic Whetstone Sharpening stone Workstone #1000/3000 QA-0124 from Japan

I have used this stone for several years now and it continues to work flawlessly. I constantly get a mirror finish on the blade of my knives and it seems to be adequate for years more in terms of how much stone I have left.When it comes to the subject of CHIPPED CORNERS, I did have a small chip in the corner of mine. I considered making this a four star review, however after reading some of the other reviews here and the fact that I am not a giant man baby who felt the need to kick his feet and put in a 1 star review as I don't seem to understand how these stones work or how to level one or how to write an ACCURATE review, I went ahead and gave it the full five stars to compensate for general lack of intelligence or normal emotional regulation amongst my so alleged peers.I hope this honest review can help someone trying to just decide what to buy and apologize if I added a bit of ego to the mix but it seems this is the trend here. I tried to include useful information as well.

Although it was shipped with air pillows for cushioning, they do nothing to protect these very fragile stones when the air pillows are just laid on top. My whetstones came with a 1 inch piece that broke off from one corner. Although it may not seem like much, once you start sharpening, you'll find that the blade catches on the corner, which causes a potentially very dangerous interruption in the sharpening motion.The quality of the stones themselves are average. They get the job done, just not as efficiently as others I have used. If you could get these without damage done to them in the shipping process, then they're ok.

This is an effective sharpening stone, with it I can put a razor edge on my Benchmade knife. It's a good option if you don't want to spend $200 on a series of different stones. It's not ideal, if I had another rougher grit stone it would speed up the process, and a very high grit stone would be nice to put on that mirror finish. With that said, it's not really worth the cost and this is all most people really need. It did arrive beat up on the edges as others have mentioned. The packaging is flawed and the stone knocks back and forth on the holder during shipment. Be careful using it, the material is somewhat soft and your blade will dig in if you don't hold the right angle. Also, it can slide on a table if you use a lot of pressure so be careful!

I use them often. They have held up great. The knives get sharp and we have avoided any cupping. No complaints.

All (4) corners of the 1000 grit side were broken off up to 1/4" from the edge. Returned product

el precio es algo alto para una piedra que al pareser no es naniwa original no tiene la marca por ningun lado creo que para principiantes estara bien en menor costo
