    Has anyone here trued a whetstone back to flat? We did all of our stones last summer and brought them back to what they are supposed to be.

    The low cost easy way is use a concrete slab,wet the concrete down with soapy water . Use a pencil to put crosshatch marks on the stone you want to true up.

    Put the stone face down on the concrete slab and scrub in overlapping figure eights. Old sort of rough concrete works best.

    I know,the job is easier than using a dinky trueing stone. Kills two birds with one stone,or two stones!

    I didn’t go to college so I’m not limited by indoctrination . Some folks throw money and some folks save it. Money won’t save you out in the woods unless you use it for fire lighters.

    Anyhow,point is ,it’s cheap ,effective and easy.

    Thanks for the tip @ManyHammers. I've got a couple around here that are so concave that I had to stop using them.

    I have to do that to my water stones regularly. Can get away not doing it for smaller knives with secondary bevels. Nothing beats a well flattened stone for a zero scandi blade.

    My Arkansas stones are all just as flat as they day I bought them. And I have used them weekly for the better part of a decade. My Surgical Black Arkansas stone hasn't the slightest bit of wear. Aside from the box, you'd never know it wasn't brand new and unused.

    I use one of those flattening stones every time I sharpen my knives. That way it always stays flat.

    If you're talking about water stones there are lots of good ways to flatten them. If you're talking corundum (not in a magnesia binder that's friable) or Arkansas I don't know of any easy/reasonable way to do it.:oops:

    There is a price range of solutions from $0 to $400.

    Concrete blocks tend to have nice flat sizes.

    I have Chosera and Shapton Glass stones, and I use an Atoma 400 diamond plate to flatten them. The Atoma serves double duty by making repairs that require a lot of metal removal quick and easy.

    You can spend more, from diamond lapping plates, on up to the Shapton Glass Lapping Plate.

    I find the Atoma 400 to be well placed on the value curve.

    I have used concrete on Norton stones but now have the Norton flattening stones. I sharpen straight razors also using Shapton stones. I am pretty picky about them and have the ridiculously expensive diamond flattening stone for them. I am aware that a serviceable edge can be achieved on concrete alone. Being associated with agriculture I remember plenty of lettuce knives that were sharpened in this fashion. I appreciate your concern regarding my finances but they are MY funds to do with as I please.

    I had the Black Arkansas stones at one time and never needed to flatten them. Waterstones are a different substance.

    I didn’t like the store bought trueing stone,too much elbow and shoulder pain. Returned it. The way I do it on the concrete feels so much better!

    You could also buy or salvage a concrete landscape block and use it at bench height. You can check it easy enough for it being flat on another larger surface that you know to be truly flat. You can get a lot of other use from it after the face is worn some sharpening things like machetes, mower blades, hatchets and axes. Sure you might not want to do your grandpa's pocket knife he passed on to you but for rough work they can take a lot of steel off. I can just hear everyone who own one of those better axes that they would never do this and that's fine but if you go easy this will give you a good working edge. If you have better things by all means use them but keep your eyes and brain open to seeing solutions for problems if you have to be resourceful.

    I recently trued up an Arkansas whetstone that I have used and abused for over 20 years. I had some "junk" diamond sharpeners like these
    image_17548.jpg and just laid them down on a flat table. I scribbled on the whetstone with a pencil, then ground away on the diamond plate until all the pencil marks were gone.
    If you've ever used oil on the stone, degrease it first! That's important.
