So i one a ebay belgian coticule for like $35 and the guy offers me another stone for $15 extra he says that he thinks its a naniwa 8000 grit 8 3/4 x 2 3/4 x 3/4 thick but he cant be 100%. What do you guys think it is and is it a good buy or no. Im looking to get a real cheap starting kit and upgrade when i get better. I would also like some opinions on the coticule was it a good buy or no it measure 5 1/2" wide and 2 1/2" deep.
