G'day SRP members & guests.

Found this listing on ebay and need an expert opinion on it.

Arkansas Sharpening Stone - Hard - Fine 7" - eBay (item 360341933590 end time Jul-04-11 17:13:57 PDT)

I have had a look in Hones section to see if this hone is listed in Hone Reviews.
I saw no entry so I need to ask the members about it.

Firstly has anybody used one of these ?
What is the approximate grit size ?
Are they value for money ?
How do they perform in honing duties ?
Are they fast cutting as claimed ?

Thanks for you time

Rick
