Process of the Polishing WorkⅠ

To study the quality of the blade we make the surfaces clear. Then we can see the details easily.
In the polishing work, there are two kinds of finishing style.

One is the classical polishing style (SASHIKOMI).
The other is the modern polishing style (HADORI).

The big different between them is in the step of NUGUI.
 


Preparation
Before starting the polishing work, we have to make the stuff for the work, HAZUYA, JIZUYA and NUGUI.
Good preparation is very important for smooth work.
 
making hazuya and jizuya
Hazuya is made from uchigumori stone. Jizuya is from narutaki stone.
Both stones are similar kinds of finest stone in Japan.
Narutaki is a little harder than Uchigumori.
The fineness of texture and the hardness is very important to select them.
Slice the stone with chisel and hammer.
Hazuya, the rectangle one is credit card size
various qualities of Jizuya, they become harder toward the right
Fix them on the paper with lacquer. The paper should be thin and strong.
Cut and shape them to proper size.
Grind them again to the proper thickness to use.
The hazuya for NARUME work is larger size and the best quality.
 
making nugui powder
Nugui is very fine powder mixed with oil.
Each polishers have their own powder making system and material.
One of them is grind the material completely with mortar to the finest powder.
Examples of the materials are, narutaki stone, tsushima stone, iron ore, oxidized iron, and other things.
 
polishing migaki needles
There are some kind of needles with different shapes for blades' surfaces.
Polish them up completely to get mirror surface on its own.
The finish of needle surface moves to blade surface.



HAZUYA
HAZUYA is a very thin Uchigumori stone fixed on the paper.

Polish the blade surface with HAZUYA on the thumb completely, especially in the hamon.
 
Then the surface becomes clean. And all the tempering effects come to be seen.


In any polishing styles, the kissaki of shinogi-zukuri blade is completely finished with hazuya stone. Because the hazuya finish is the best way to see blade quality. Therefore forebears said "study the kissaki carefully to know blade quality".
