A good stone of this kind , turkey origin not India , is amazing finisher , even the Esher thuri canot give someting more to the edge . I have 3 hones of this stone , and they are stunning finishers - they give very smooth and very crisp and sharp edge . I get 2 more of them the last week and im very hapy with them . They required a perfect lapping and they work with water mixed with liquid soap or dish washing soap . You can use carosene ,or beter WD 40 . The oil makes them slower , i prefer water . You will not be sorry about those stones , they work amazing and the only thing is that , they required presure - light to moderate . Without presure are slower like all hard stones . But they are many times faster that the chnese 12 k .
Lidyte is actualy a black JASPER - Basanite .Very consistant , fine and abrasive - you can see the metal tracs on the surface of the stone after few strokes . They are not expensive stones , but they are polishers anf finishers of highest class .
Black Lydite is called "Touchstone"
