One question, in your write up you said that the coticules are graded from 1-4 (up to Kosher) based on their appearance, but this has nothing to do with their performance. In your past write ups you seemed to suggest that you had several coticules performed significantly differently from one another (most or all left a similar scratch pattern, but they cut at very different speeds). At this point do you think that there is any corrolation between a coticule's performance and it's appearance; and if so what do you look for (now that you are one of the forum's experts on these stones
). Otherwise, is the only way to find out about the stones performance to compare it to other coticules via testing. Maybe you already answered this in another thread, if so then can you kindly provide the link.
Thanks,
David
