Nakayama Kiita Koppa Toishi with handmade wooden Toishi dai!

Another superb example of Nakayama Kiita. Even has a chunk of full thickness black Nakayama Kawa on the left corner shown in pic 3, which has at least a large crystal that along with the smaller ones give that rare Nakayama Sparkle in the sunlight unique to Nakayama Mine. It has kesuji (non toxic hairlines- not cracks) that are safe to hone on, and do not catch my razors edge. They do not extend to the sides, and by the gradient coloration of iromono colorations that bask the surface of this toishi in a diffused pink orange sunset glow compared to the differential stark contrast of pure kiita coloration without iromono deposition along the kesuji- it has been this way and stable for thousands of years, likely much longer. Definitely before it was mined and slabbed and made into this vintage barber's awasedo.  

However I feel it my duty to tell you that kesuji like this, can in some cases take on water, and in a fraction of those cases, it has been shown for it to be possible that the water can cause a crack to occur.  Just like stones with unsealed sides- it is rare, but it does sometimes occur that those too can crack. I am comfortable with this offering, as it is a color and quality in honing feel of Kiita I almost explicitly retain for my own private collection, and I enjoy honing on it so I will be happy if it never sells. Give me this over a Maruichi any day.

The weight and size alone are worth this much if sliced up as Nakayama Kiita nagura, but this toishi is a spectacular hone and worth infinitely more as a cherished honzan for razors. The price is lower than kesuji would warrant, and it is so because I want to share the opportunity to own a great kiita and razor finisher and help dispel some recent phenomena and rumors that a super hard stone is needed to finish a razor. Up until just recently most really hard stones were seen as defective, and were not valued. Kiitas have always been monopolized by the emperor to sharpen katana and nobility. They are also the most sought after coloration in Japan today along with Karasu.  It depends on the steel and blade geometry and desired edge preferences and the hand and preference of the sharpener most on which hardness or stone is best suited for the task.
