Tamahagane SN1118

Features

Manufactured by Kataoka and Company in Niigata, Japan.
The 3-ply stainless steel has an original thickness of 20 mm and is thinned by repeated rolling to a thickness of 2 mm. You might want to look at this rolling process as a modern forging technique. Also, this rolling process removes all the impurities in the steel leaving you with a very hard, very pure stainless steel. After the rolling processes, the V-G No. 5 cutting edge reaches a hardness of 58-60 degrees on the Rockwell scale and a final thickness of .65 mm. The outside layers each reach a thickness of .675 mm.
There are several different VG stainless steels. Kataoka selected V-G No. 5 stainless steel for the SAN knives, because V-G No. 5 can be hardened as hard as any of the other V-G steels but has superior edge retention. Using scientific testing equipment (CATRA), Kataoka was able to show that their knives stayed sharper longer than knives made from other VG steels.
The edge on the SAN knives is a minute, beveled edge. The angle of the edge is between 14 and 15 degrees. To appreciate the quality of the edge, you must first look at its incredible mirror polish and then try cutting with it. Kataoka has achieved the perfect balance between sharpness and strength with the SAN edge.

The SAN KYOTO knives are balanced with a stainless steel weight which attaches to the tang and is visible at the heel of the handle. Not only does this add to the beauty of the SAN KYOTO design, it also creates fantastic balance.

Tamahagane SNM1118

Features

Manufactured by Kataoka and Company in Niigata, Japan.
The knife from the Tamahagane SNM series is 3 layers of steel: the middle of the blade is made of hard, but fragile VG5 steel, which is supplemented with 2 layers of mild steel, making the blade very strong, hard, but at the same time retains its flexibility and does not lend itself to distortion and kinks. The knife is fully balanced and very easy to use in any kitchen.
After the rolling processes, the marerial of VG5 becomes harder and harder to be 61 degrees Rockwell Hardness in the final thickness of 0.65 mm. Meanwhile, the two outside layers of SUS410 will remain at 28 to 32 degrees to strengthen the blade and protect against damage and corrosion.
Sharpness is is the outstanding feature of the knife. The blade is sharper and remains sharpness longer than normal knives.

Tamahagane SNMH1118

Features

Manufactured by Kataoka and Company in Niigata, Japan.
The 3-ply stainless steel starts out with a thickness of 20mm and with a modern repeated rolling-forging technique, it is thinned to a thickness of 2mm. This rolling technique also removes all of the impurities in the steel resulting in a very hard, pure stainless steel. After the rolling process is completed, the VG No.5 cutting edge obtains a hardness of 61 minute degrees on the Rockwell scale with a final thickness of 0.65mm, while the outer layers each obtain a thickness of 0.675mm.
The edge on the SAN knives is a beveled edge with the angle being between 14 and 15 degrees. When you look at the awesome mirror polish and try cutting with it, then you will appreciate the quality of the edge. Kataoka has once again achieved the optimal balance between strength and sharpness with the SAN and SAN TSUBAME Knives edges.
The blade of the SAN TSUBAME is hand-hammered half way down from the spine. The whole blade is then sandblasted but this technique only affects the soft SUS410 stainless steel outer layers thus leaving this layer with a matte finish and the core VG No. 5 with a mirror finish. The sandblasting and hammering process gives the SAN TSUBAME a highly rich appearance.
