Waterstone, 220 grit, 1" x 3" x 8" in Blue Plastic Hinged Box by Norton Abrasives - St. Gobain

This is great when you need to reset the angle or repair a nick. Saves a lot of time when compared to the 400 stone I normally start with. The one I got had a “break in” period. When I started using it, it did not cut well at all. But by the time I was on the 2nd side of the first knife I used it on, it started cutting much faster. With this stone I only need to spend about half an hour to change an angle on a good chiefs knife. Of course I only need to use it the first time. Resharpening dosent require this fast cutting stone. This is the best very corse stone I have ever used!

I have some dull chipped knives. They just are not worth the cost to sharpen them. I had a Chinese cleaver that was so dull, it was a paper weight. This stone is fantastic, especially for the price and size. Soak the stone for 15 minutes, then have plenty of water by you to keep both the stone and the knife wet. It's the slurry that actually sharpens the knife. This is only for knives that have chipped edges or absolutely no edge at all like my cleaver. Take the time to watch some videos on youtube. There are a few different techniques shown, but my favorite was a guy speaking Japanese but you could watch the movements he was making.

Awesome for sharpening kitchen knives

I use this stone for removing chips in the chisel edges and to reset a new bevel angle. It’s a nice addition to my other stones and will keep my higher grit stones from too much wear too fast. It comes in a nice blue plastic case for storage. I only wish Norton made these slightly larger but it works fine for its intended purpose. Good value for the money.

Got this to flatten chisel faces and shape chisel and plane bevels. Well, I just flattened 9 chisels in record time. My coarse diamond stone will now be used mostly for flattening my water stones. This stone cuts very fast and very well, but goodness does it wear quickly. It makes a huge messy slurry in no time, and if you flush that it cuts very fast. The only thing is that it seems to need flattening every couple of minutes of use. Make sure you have some way to flatten it or you'll be putting curves in everything you try to shape. It's worth it for the time it saves though.
