Norton24335 Japanese-Style Combination Waterstone 220/1000 Grit 8" x 3" x 1" Knife Sharpening Stone

I have some a experience with waterstones from a few manufacturers (King, Shapton, Naniwa, Suehiro, and others). My original experience however comes from oil stones(Arkansas, India, Crystolon, off brand). Compared to a lot of what has been said in reviews here, the stone has surprisingly a hard feel. I believe that it is vitrified as it feels that way. Harder feeling stones are better for creating sharper edges than softer feeling stones. Most people compare waterstones as hard and soft, and fail to separate the characteristics of feel on the stone and durability of the stone. In terms of durability, the 1000 is better than expected. The 220 is as expected. From Norton's own description, they claim that their waterstones are softer than oilstones and are designed that way so that fresh grit is constantly exposed for faster sharpening with low pressure. I find this to be that way that waterstones are designed by all manufacturers. However, that doesn't mean they are equal. For example, the Naniwa stones I have used have been rather soft in feel. Durability varies according to the product line though. A stone feeling soft will lead to gouging of the stone on occassion and inhibits the formation of the sharpest apex. The sharpest apex will be created on hard feel stones. Durability also plays a part however. Low durability stones grind fast but will not create a sharp apex like highly durable stones( due to slurry hitting the apex). An exprienced sharpener will know how to somewhat mitigate this. High durability stones grind slower if the person sharpening is not experienced, however, they will form a sharper apex(minimal or no slurry to damage apex). Both sides of this stone perform according to how they should be designed. I tried with a new POS chisel that was $3. I knew this would required a lot of work to flatten the back and get into good shape. I used the 220 to start the flattening. It took quite a while( over an hour). However, I sharpened until I had enough flatness behind the edge. The stone auto-slurried as was designed. A lot of people complained that the 220 was too soft, however, I found that there was no noticiable decrease in the height of the 220 portion of the stone when I was done, despite the fact that there was a lot of slurry and I had used it almost an hour. I feel that the amount of slurry created however was appropriate for the task of a 220 stone where its goal is to grind as much metal as fast as possible. A lot of people say that the Shapton 120 wears down like nothing. I have found that King stones give off a lot more slurry than this 220. Some reviewers claimed that it was uneven after usage. I find that if you make sure you are using the whole stone when flattening the back, the stone remains level. Usually a stone becoming dished is due more to the sharpener than the stone. Those same sharpeners are more likely to dish other stones as well. In my opinion, I find the 220 performs perfectly for it's intended use. Also consider that you can get a full sized Norton 220 8x3x1 for less than $40 which will be unheard of elsewhere. If your coming from oilstones, expect waterstones to wear, that is what they are designed to do. The 1000 grit side works perfectly fast. I did not see any slurry produced and it didn't take long either for the back or the bevel. Without slurry(higher durability), cutting fast, and hard feel makes the 1000 grit side ideal for apexing and sharpening.Overall this combo stone is very well designed, performs well, and if I had to own one stone, this combination would be the most important for knives. For woodworking, this would be a fine starting place.

Great stone all around! It comes in a nice, heavy duty box which is for storage as well as a base to sharpen on. It also puts an edge on my straight razors like no other stones I have used. My favorite thing about it however is the size... it is perfect. Finding a stone wide enough to use without having to use the X pattern is difficult. The Norton is perfect for the price, I have seen stones not as high quality sell for much more.

This is a great stone to own, especially if you're just wanting to try out water-stones and don't want to spend a heap of money right off the bat. The 220/1000 combination is said by some to be impractical, but that's in the face of many people who sharpen in that exact progression as well as Norton's own designs for these water-stones. Their other stones also skip from 1000 to 4000 to 8000, much steeper than you will see in other water-stones, but the grits are meant to work with each other. I've found no real difference when mixing a 325 and 750 grit in between the 220 and 1000, you just wind up spending more of your time you could have spent just transitioning to the 1000.The only thing that I don't really like about the stone is that it requires flattening a lot, the 220 side specially. The more you flatten, the faster the stone will wear away. Mine is actually about half an inch thick now because I dished out the 220 side repairing a blade and had to remove so much to get it flat again. This might not be an issue for those that can find the flat spots to grind on, but I think if you're going to be sharpening a lot on the 220 side it might actually make more sense to just buy the solid grit 220 stone since you will need to flatten that side much more.As far as how sharp it gets... There's way too many ego-inflating, nonsensical "sharpness" tests, and I'll tell you I've achieved most of them with just this stone alone. It will easily produce an edge that will "push-cut" through newspaper or cleanly shave hair off of dry skin with no flaking or catching, and will even split and whittle them if stopped a little afterward. In the end it really depends a lot on your technique, skill level and how much you want to invest polishing a blade on a 1000 grit stone--it can definitely be done, but mistakes are a lot costlier on 1000 grit than 4000.I really like the plastic case that it comes in too, makes a great non-slide sharpening bench to rest the stone on too

This stone is quality made and came with a neat plastic case to store it in and sit it on while using it. It has corner retainers on the top to hold your stone in place while using it.I quickly found the drawback in using waterstones, the wear factor.The 220 side wore a "dish" in it after honing just one chisel (a new Stanley FatMax) and I realized this stone was going to wear out quick after truing it back up after each use.I remembered 3M makes a Wet or Dry sandpaper that's much cheaper and so I bought a square foot piece of granite floor tile from a local home improvement store along with some 3M General Purpose Spray Adhesive.The Wet or Dry paper works GREAT and I've since purchased finer grits of it as well and ditched using the wet-stones all together since they wear fast and are pricey.The sandpaper method is much easier for me and cheaper, but I suppose it comes down to a matter of preference.These stones are of good quality, so I can't speak negatively of them, but not sure they're the best route for sharpening chisels/planer blades over using wet or dry sandpaper glued to granite....
