Just perusing the many items I am in need of in my shop and the lack of funds to acquire them.. while looking at sharpening equipment I saw a flattening stone, another $30 us to add to the deficit..

Then I had a thought..

I noticed that these flattening stones (used to flatten off the face of a water stone) are silicone carbide, the only difference I can see between them and the cheap silicone carbide stones available to me here are the diagonal grooves across the face that allow the slurry to escape ensuring a flat surface on the waterstone being tuned. Was thinking it may be quite easy to groove a standard cheap silicone carbide stone that would cost me no more than a couple of dollars here to perform the same function, perhaps using a guide and a hacksaw blade or similar. Anybody tried it, good idea or not? When I actually have some decent water stones, rather than the cheap silicone carbide number being my only sharpening tool, I am going to give it a try.

how about a flat plate of glass and a sheet of sandpaper. trues my stones just fine. use a coarse wet/dry paper.

Ok, thanks, that would be simpler still… I was just going on the stated claims that the grooved stone avoids a build up of loose material between the stone being flattened and the stone doing the flattening which could then cause an uneven surface. I guess you haven’t had this problem.. are we to assume that the grooved flattening stone is another gimmick product that serves a non-existent purpose?

Which flattening stone are you talking about? Not every stone is made the same.

I heard they work fine. But they do not stay flat after a while.

If anyone here does not want to flatten their water stone always, then I suggest you buy CERAMIC water stone.
They cost more, but requires few maintenance.

I do my flattening near the sink and rinse fairly often. my problem is the flattening stones don’t stay true. and a dedicated quality flattening plate is expensive. if you want to go that road, shapton does make a good diamond impregnated bronze flattening plate. but it is very expensive.
