Hello , I have this stone for a while, bough it on ebay from USA. It is 5 long and 1 1/4 wide. It is extremely soft, like Escher,
But leave a much sharper edge than an Escher. I use it just with water, 25-30 x strokes are enough to improve a Naniwa 12k edge. Slurry is orange color. The sharpening felling is exactly like Escher.Name: WIN_20140813_143432.jpg Views: 262 Size: 53.4 KBName: WIN_20140813_143634.jpg Views: 253 Size: 56.6 KBName: WIN_20140813_143441.jpg Views: 248 Size: 55.1 KBName: WIN_20140813_143509.jpg Views: 253 Size: 56.3 KB
