Cerax #320 by Suehiro

Extra large whetstone...works fast to sharpen a blade but you have to know what you are doing. Effective once you figure it out. Much better quality than the other brands. This is the real deal. You will only ever need to buy this once for an industrial kitchen or workshop. I bought several grits. Expensive but good tools cost!

Definitely a good ceramic whetstone. Cuts fast, and stays relatively flat if used properly with the correct technique. This stone will get your knife roughly sharp as well as getting a new edge.This stone is only meant to be the first step in the sharpening process. Use the cerax 1000 grit stone after this one to get a true sharp edge.

I'm a handy man that goes through work knifes fairly often. I just started using this wet sharpening stone this year.I'ts a little messier than the usual diamond stones, requiring a little more time. But I think this wet stone actually takes the knife edge down a little faster. And it leaves a little smoother, more polished, edge.I'm still learning how to make the best use of this ceramic stone. Since it requires a little more set-up and clean-up time, I usually line up a few knifes that need maintenance, then use the wet stone.

It took me some time to make a review since I want to use it first. I used it on a fairly good Chinese made knife. I think it's Rockwell harness is 56 to 58. I dulled it using a brick and I mean really dull. Using the stone, it makes slurry fast. The slurry is made with just a pass. It's softer than expected and it removes material slower than expected. I made 5 passes with it before it made the result I needed. I then used it on my Japanese knives with a Rockwell hardness of 62 to 63. It works even slower on these.So final verdict for me is that it is not worth it for those who are on a budget. I used a 400 grit Chinese brand that cost me 5 bucks and it works slower than this but the result is still the same. You just need to be patient.

Disclaimer: my review is based on sharpening an extremely dull set of German steel knives and a very soft metal dull set of "no name" knives. Both belonged to a relative.The Cerax 320 is a softer, grittier stone designed to quickly reset a bevel and cutting edge. The 320 removed knife edge dings and reset the bevel very quickly on knives that had never been properly sharpened. The sound and feel of the stone is like sandpaper on the knife. The edge was then set on a Cerax 1000. Each German knife only took 10 minutes, start to finish, using both stones to make razor sharp.The 320 grit was too aggressive for the soft, cheap, no name knives. A burr formed after only 5 push/pull strokes.I would not use this stone on my own knives that have been properly stone sharpened and maintained. It is in my knife sharpening arsenal for friends and relatives who use my knives once and ask me to sharpen theirs.

Awesome for overcoming my rough chisel chips. Beautiful box and no regrets.

Quality diamond stones are all the rage these days but if you want some good old fashion whetstone, this is about as good as they get.

I started hand sharpening on a King 1000/ 6000 grit stone for hard knives based on online reviews. It became clear that a coarser stone was needed when I let my knives get medium dull. This has made sharpening so much faster. Get a burr quickly then move to the higher grits.More than one reviewer picked this as the best coarse stone and I am very pleased.
