Hi Jarrod, earlier in the year I bought a curved coticule. Since then see how you have coticule naguras that are reverse shaped, where using them helps keep the stone curved longer. In any case mine did not come with one (and i did not expect it to because it was not in the description) Any chance you could put a reverse curved nagura on teh shop or could I commission one for you. I do not have the tools or the capabilities to do so on my own. Thanks and keep up the great work!
It is best to get some sandpaper and shape it exactly as your stone is, that's how I do them, one by one on their paired bench stones. All you need is a piece of sandpaper big enough to cover your base stone, a pencil and some time. Cover the bench stone with paper, grid up the rubbing stone, and then rub the nagura piece on there w/o letting it yaw around (= keep however it is oriented to the length/width of the bench stone the same). It'll take a few repeat sessions to get it to bleed the anti-curve all the way to the periphery of the rubbing stone, but the anti-curve will start in the middle of the rubbing stone and bleed toward the edges, you don't need the whole stone to assume the shape because the portions that don't get rubbed off of the pencil grid are 'below' the other part doing the work.
