    Hi Ken
    Not to pull this thread OT but why not diamond? All I've ever used were diamond and my whetstone's, but after years of reading through these threads, I just don't see the appeal of water stones.negatives as I've read them below
    1)have to have a sink pond, soak,etc
    2) may need another stone to create a slurry
    3) goes out of flat alot / consistently (or maybe it's made a big deal more than in reality)

    In my simple mind, why not use diamonds for all the course, medium, fine? (As far as I'm aware they don't really go out of flat?) and then finish with a natural or whatever superfine finish / polishing stone. That way for the course tasks your not always flattening stones.

    I typically only use 300,600,1200 diamond and then sometimes hard black Ark or diamonds and then strop. Seems to pop the hairs right off my arm.
    Thanks

    Michael,

    I'll start by saying diamond plates can produce very sharp cutters as can almost all sharpening systems. Back in the day a workman would pull out his dished carborundum stone spit on it and in a minute or so be back at work. So bottom line I'm getting into the sharpening weeds.

    In today's sharpening world we have so many options, each has strong points and weak ones. Notice I'm stuttering around trying to not be dogmatic but what the heck, cut to the chase.

    Diamond plates, diamonds in general can make good course abrasives but because of the shape of the diamonds they leave scratch patterns that are hard to remove. In addition several makers plates may have rogue diamonds that leave very deep scratches that may be impossible to remove with your honing stone. Where this becomes important is at the cutting edge. The goal of the polishing stage is to smooth the scratches left by the honing stone and smooth and decrees the size of the saw teeth on the cutting edge as much as possible. The smoother and smaller those saw teeth are the cleaner you iron will cut and the longer it will last as a cutting edge before needing to be re-sharpened. BTW, some of the most popular water stones, while the bevels and backs will shine so brightly as to be almost blinding, have the same scratch problem with ordered and relatively deep straight sided scratches from even their 16K stone.

    If what you are doing works I'd stick with it, only sharpening nerds like myself worry about scratch patterns and the like.

    My final stone is 12k shapton. That was the one available at decent price ($50 or so) on Amazon.

    It worked so never switched. It works fine paired with strop for my skill level.

The only stone you might wear out would be the med India. Some times it is good to strop, there are too many options to go through but almost any piece of leather on a board will work.

    For any sharpening you need to be able to grind (the med India), hone (the soft Ark), and polish the Black Ark). Learn on a 2" wide stone it will teach you to use the whole stone.

    If money is a problem you could go with the Hard Ark for $36.97 instead of the Black Ark. While I have never used that stone I have the Norton Hard White Ark stone and if I were to use it as a final stone I would also use a strop with green stuff.

    Exactly what I needed, thank you!

    That's mean!

    PS- Maybe he meant buffalo wings and that's how he got the Cholula on his shirt. He's really way ahead of us.

    And Dan claims that their Black is finer than the Translucent, and it costs less as well.

    My only comment on this is if you can afford it, get 3" wide stones. If you have a jointer plane you will appreciate the wider stone.

    Of my Dan's stones, the black is finer than the translucent.

    My 'rogue' translucent stone is every bit as fine as Dan's black Arkansas stone.

    A smooth piece of jasper is also a close match.

    Jim,

    I suggested 2" stones because the narrow stone will help train to use the whole stone, to "hang ten" when sharpening. When I work on wider stones I find I have to force myself to use the edges, which BTW, was one of the Cosman finger nails where he said to stay away from the edge of the stone.

    BTW, my experience is the same as yours, my "Black" from Dan's is finer than my "Translucent". The Translucent feels almost like a honing stone where the Black is incredibly smooth.

    I've heard conflicting reports on which is finer, probably because the surface finish (how worn in) of any individual stone is a bigger factor than whatever small differences in density there are.

    I think translucents are cooler-looking, and I like that you can see the swarf.

    My first sharpening stones, not including the ones I used in Cub Scouts, and Boy Scouts, came from Smith's. I called them on the phone, and they sent the stones C.O.D. That was probably in 1974, or 5, but I don't remember exactly. These were a set of four. One of each grade they sold-Washita, Soft, Hard, and Black Arkansas.

    The Washita is a purple, merled color. I've never seen another one like it, and wish I could find one now. It cuts Really fast. It's almost worn all the way through around the center.

    I still have these stones, and use them occasionally. They were thrown out of a shop of mine that was hit by a tornado in 1988. Two were broken, and one piece of one of the broken ones was never seen again.

    I used those until about 1992, and past then occasionally, when I bought my first water stones-Nortons-since moved on to faster, finer water stones.

    The Black stone had never been cleaned, and sometime about ten years ago, I got the idea to clean it. It had always been black until that cleaning. I don't remember what I cleaned it with, but may have been carb cleaner. At that cleaning, all the black color left, and it's now translucent. I expect they put black dye in it for marketing reasons, but don't know. Smith's stopped selling full sized stones decades ago.

    That finishing stone changed my life in learning what Really sharp is, and how such a sharp edge can effect work done with a cutting edge.

    Back then, when I was a young man, I carried a Soligen steel pocket knife. After taking two people to the hospital, who asked to borrow my knife, and in spite of being warned how sharp the edge was, I quit carrying it.

    Sometime I decided to buy another set of Arkansas stones. I had always wanted larger stones, so got a set. This set has a real black, which was the finest they sold. It does not put as sharp of an edge on as the old Smith.

    The black Arkansas stones sold by Dan are finer than his translucents. There's no confusion about it, that's how they are described by them. Whatever other vendors do and label is a different story.

    I have both from Dan's. The translucent cut faster than I expected for whatever I last used it (don't remember if it was a knife, chisel, or plane blade). I have more of his Black stones since I have them in different sizes.

    If you buy the "best" brand, they claim that their translucent is the finest. Their claim is based on looking at the resulting edge. I am not sure how Dan graded them, but I will blindly assume it was density; so just a guess.

    I have not had complaints about the translucent or the black and for sure, it is really cool when you can shine a light through your stone!

I'll also note that I sharpen often but I'm not particularly "into" it, just get it done and get back to work. At least at this point I don't intend to spend many hundreds of dollars on sharpening equipment.

    I too work in a space without plumbing, so while my current setup works okay I'd like to move to something that doesn't require water. The world of natural and oil stones is totally new to me though (and seemingly complicated), and I really don't know where to start on sussing out a system that would work for me. My questions are 1) is there an authoritative source or thread(s) that I could read through that explains the world of natural and oilstones? And 2) do you have suggestions for a reasonably-priced system/set of stones that doesn't use water?

    Thanks in advance, I'm hope I'm not coming off as wanting you to reproduce a bunch of info that already exists - I'm just a bit lost and looking for a nudge in the right direction. Much appreciated!
    Shapton Pro and Shapton Glass stones are spray and go, no soaking. These are probably closest to what you currently use. If you have a spray bottle with water, you can wipe up the mess with a towel or paper towel. The Glass stones should cut faster than the Pro stones by design and be more able to handle the fancy steel blades these days.

    Diamond will cut anything. You can use a diamond dry or with water. I use Smith's honing solution, which then leaves you with something to wipe up, but, you do not get over-spray from the water bottle. Some people don't like diamond because of the strong scratch pattern it leaves. I have also used Gatco honing oil for Diamond stones, but Smith's is my go to here.

    Spyderco bench stones can be used dry, but most people I know prefer to use them with water. They can be tough to flatten but after you flatten them (if it is needed) they stay flat for a very long time.

    Arkansas stones. I use honing oil, many people prefer to use other things (such as kerosene, simple green I think, water....). These are probably one of the slowest cutting stones, especially on fancy steel. I don't think that I would use these to sharpen a damaged blade, but they work fine for anything I have. Note I have not attempted to sharpen my knife made of CPM S110V steel. My expectation is that it can be used to maintain that edge but if it is really dull, I doubt an Arkansas would be up to that task.

    Norton Crystolon. These are fast cutting (silicon carbide) but leave a rather rough edge. They also dish easily and can use a lot of oil and be messy. Inexpensive. Messy.

    Norton India. These work well, and many people love them. They cut most things and leave a finer edge than the Crystolon stones. They use aluminum oxide. You need oil and it will be messier than the Arkansas stones. These are very inexpensive. Some people keep a Crystolon for the rough stuff and then refine the edge with the India stone. Messy.

    If I am using a Crystolon or India stone, I use a 14" rubber coated bar tray to contain the mess. I use the same try to clean my saw blades. $12. I use Norton honing oil with these. I do have mineral oil that I have used, but some people indicated that it can be hit or miss because the Norton honing oil, although mineral oil, is specifically refined to have smaller particles so that it is less likely certain things will evaporate out leaving a sticky mess in your stone. I have not had this problem with the standard mineral oil that I have, but when I use my standard mineral oil (kitchen grade, I purchased a gallon of it, of course I also have a bunch of Norton honing oil) I can't say I would lose much sleep if it gummed up my cheap Norton stone.

    https://www.amazon.com/gp/product/B0032AM0S0


    I do have other stones as well, but I have not used them; for example, a Norton Clear Creek bench stone (https://www.amazon.com/gp/product/B00DSW6TMA). it used to be called a Queer Creek stone but since the word Queer is almost never used based on the original definition of "odd" or "unusual", they expired the name in 2006 and changed it to "clear". Think of these as slightly lower than the No. 1 Washita and you can use it with Water or Oil. These are also called "Ohio Blue Stone" since they are mined in Ohio then shipped to Mexico for processing / cutting. I would have to check, but, if you use it with oil, you cannot go back to water. 600 to 1K grit I believe.

    I purchased a few American Mutt stones, but it is so out of flat that I would never use it on a blade I cared about. More useful for a lawnmower blade or similar. But it should cut fast. Might use it on an Axe head.

    If you just want a random collection of facts that I assembled for my own use, I can shoot you a document that is focused on the stones that I have, but contains a lot of info.
