I've been straight-only for about 6 months now but I have nooooo clue about coticules/japanese stones/etc.
I know they are very expensive, but that's about it.
Sooo this is my request..If anyone has the time and knowledge, could you fill in us noobs about these stones. What do they do, why should you get one, why does an irregularly shaped chunk of rock cost so damn much?
What prompted me was seeing Joel's $500 Japanese Stone in B/S/T. I have no doubt that it's worth the money and it kicks ass, but how and why?
I really am 100% clueless, so any knowledge you can throw my way would be greatly appreciated.
