The abrasive particles in the Shapton stones are very consistently graded for optimal performance. In some grits, the particles are within .01 micron of one another. In other words, each particle is the same size. This uniform size allows the stone to sharpen faster and create a better finish. If a stone is inconsistently graded some particles are larger (thus providing a coarser edge) while some are smaller (slowing down the sharpening process). In usage we've found Shapton Stones to be very consistent and true to the specified grits.
All sharpening stones can be placed into two categories. Either natural, having been quarried from the ground, or synthetic, having been been manufactured. Before the industrial age, all sharpening stones were natural by default. Simply picking up a piece of common sandstone and stroking it along a sword blade may have been enough to produce an edge. This would at least remove some of the worst nicks and gouges produced by the clash of steel.

Meanwhile, if you want something that you can use to sharpen a variety of knives and edges, including small and pointed tools, you might want to consider the DMT WM8CX-WB 8-Inch Duo Sharp Plus Bench Stone – Coarse/Extra Coarse with Base. For less than a hundred bucks, you can even use it to repair a damaged edge because of its extra-coarse diamonds.
Natural sharpening stones are those that are quarried from the ground as a crude slab of rock, then cut to size to adopt the familiar rectangular shape. At one time, these were the only sharpening stones available and there were many different types, most of which were in use locally in the country where they were produced. Natural stones are still available and command a premium price, for example, Arkansas stones from the USA.
This table outlines Shapton's recommendations for the choosing from the variety of stones in their line, the right grit sizes, and the gradations in which they should be used, to properly sharpen different kinds of knives and tools. The Japanese names for the various knives and tools are listed in parenthesis, which can be helpful for matching a blade with the right stones when one knows the Japanese name for the tool.
The DMTs are on their own scale, since they rate by "Coarse" "Fine" etc. They give micron sizes in their sales literature, so I've added a column for them. When I get home tonight I'll post up the new version that has those. New version also includes the Spyderco Sharpmaker rods, per another request, and the Trizact grading system for the 3M belts. It will also include the grit sizes for the WEPS stock plates.
✅ SAFETY : We understand the importance of safety when dealing with sharpening tools, your purchase comes with Silicone base for holding the stone inside Non Slip Bamboo base, this setup will ensure the stone is FIXED IN ONE PLACE while sharpening. And knife sharpening angle guide allows you to maintain CORRECT ANGLE and safely apply consistent pressure while sharpening the blade.
Aluminum Oxide stones range from 150 grit to 280 grit and cut aggressively but not quite so much as Silicon Carbide. The medium (240 grit) would be considered "coarse" for sharpening kitchen knives, and the fine would be considered "medium". They are considered an "oil stone" but work just fine with water, Unfortunately Norton's stones come pre-oiled so I'd scrub it well with a strong kitchen cleanser before each use until the oil is mostly gone.
We have been in the sharpening business since we opened our flagship location in Cambridge, Massachusetts in the Fall of 2012. Our standard wet-sharpening service provides a high quality edge using water cooled sharpening equipment. Our whetstone hand sharpening service was introduced during the Spring of 2015. See the details of each service below to determine the ideal option for your knives.
Overall I am very satisfied with this purchase, workmanship on product is very good. I have used it on several kitchen knifes and obtained a very sharp edge. But this does take quite a bit of time and effort on each knife. I did not give the product 5 stars because it is already showing a good deal of ware but still works great, and maybe my expectations are not sound. I would recommend this sharpening stone, but you must remember, using this type of stone you will send a good deal of time on each knife.
