Grit Test for NAKAYAMA #20
|
NAKAYAMA #20 MARUKA AWASADO 207mm x 76mm x 28mm A very pure stone with a high grit rating but a bit softer and easier to use. The grit is in the 40,000 to 42,000 range and with the fast cutting speed you can achieve a bright finish to the hagane along with a gorgeous fine polish to the jigane too creating just the right kasumi look. The stone as a full skin on the back and one side. Reads on the stone top from the upper right down, JUN SHOSHIN HONYAMA (pure specially chosen original mountain) which is a registered trade name, And 2 (an inventory or grading number) And at the middle SAIKOKYUHIN (very best quality) This Nakayama Maruka awasedo toishi stone is NEW/OLD stock from a closed store in Japan. It has not been used other than to test the quality at one edge of the stone as you can see in the photos. You may find other references to the Maruka Nakayama mines on the internet. This mine was known throughout its history to produce the finest awasedo finishing stones in Japan and probably in the world. The registered stamp on the top of this stone and the single toothed fine saw marks help to date the stone to before WW2. This is an actual Maruka Nakayama awasedo, it is not a fake. Stones of this color and varity have not been mined from Nakayama for well over half a century and they never will be mined again as these rare deposits are depleted. The mine was closed in the 1960s, and up until that time the stones hauled out were of lesser quality. I will not be able to replace or offer these stones again. This is a medium hard stone and it is easy and a pleasure to use. The very hard stones are more easily used if a diamond nagura but this stone will build its own paste and this paste breaks down into finer grit particles which continue to cut just as aggressively.
