A-1 rating for conformation, this asagi has all four corners and sits dead-flat on a table even though the back has a full kawa skin. There are no cracks or inclusions, The stone rings true when lightly tapped with a mallet.
The asagi color trends towards green, when wet it will look darker, and the general underlying pattern is a wisp of streaking cloud from end to end. Circular saw marks on the ends and sides suggest it was shaped early to mid-20th century.
The size of the stone is 196x71x30mm, weigh 1015 grams.
 
I have extensively tested this stone with razors and knives and it will cut with hone with little effort, Zowada Timahagane, classic Brian Brown, Towa from Japan, Henckels Friodur, vintage Wade & Butcher (Celebrated wedge), and even Gold Dollar razors to shave ready status. These same results will hold true with a host of tool steels. Testing with your own tools and knives is imperative.                                                                                                                                            Money-back guarantee minus the shipping.
