## Description

The Norton flattening stone for waterstones is precisely level, with a hard bond, to maintain the flat surface of waterstones; coarse-grit silicon carbide gives it maximum cutting power, and diagonal grooves on one face provide channels for material removal. This flattening stone measures 3/4 x 9 x 3 inches (H x W x D), which makes it suitable for flattening any waterstone with lesser dimensions. (H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.) The plastic case protects and stores the stone.Flattening stones are abrasive rectangular blocks used to smooth the sharpening surfaces and flatten the depressions that repeated use wears in water-lubricated sharpening stones (waterstones), to prepare them for effective sharpening of knives or tools. Waterstones have a finer grit and softer bond than oilstones, and use water as the lubricant to develop a slurry, a thin paste of abrasive grains and water that removes metal with less pressure than oilstone requires. Because of these characteristics, waterstones wear concave with use, and should be flattened periodically for best performance.Norton Abrasives manufactures sanding, grinding, and polishing abrasives, and has been located in the United States since 1885. Norton, now a brand of Saint-Gobain, meets ISO 9000 and 14001 certification for quality and environmental management standards.What’s in the Box?Flattening stonePlastic caseInstructions

Review: Works well - Most lower priced options sometimes come bent from the factory and can be a lottery. This was perfectly flat. It remains priced on the lower end but does the job well. Decent size, overall a good flattening stone. Would buy again.

*by D***C on 29 October 2019*

I'm an old-timer, well into my sixth decade, and also a third generation craftsman. My dad and granddad both had oil stones and by choice, and also virtue of my occupation in the metal trades, I have acquired well over a dozen different oil stones, some of which have suffered neglect. I was torn between this product and a diamond plate but settled on this Norton Flattening Stone. Man was I ever surprised at how well this thing works - and fairly quickly too. My first test was on an India Oil Stone and I used it dry, without any water. It was easy to see how the diagonal groves filled with dust from the India stone. The grooves clean out easily with an old shoe brush. BTW, all oil stones were pre-cleaned with brake cleaner prior to grinding. I make plenty of custom stones for hard to reach areas and this flattening stone works wonders for dressing a surface flat after a rough cut with a diamond wheel. Subsequent to my dry test, most all of my work has been done with water and a few drops of dish soap in an old steel baking pan. If you are working in your wife's kitchen sink you better protect it from the grit which will ruin porcelain or stainless. There seems to be some obsession in the comments regarding the degree of flatness. This seems odd to me but whatever. Oil stones and water stones are for hand sharpening - it's not a precision surface grinding operation, and the advantage here is that the craftsman can (if he or she chooses to) use a little "English" on one side of the stone or the other. To each his own I suppose. Negatives: it comes in a cheesy thin plastic box which does not allow for venting of the moisture in any meaningful way. If they must use plastic, use a proper "alloy".
