Tamahagane Boning Knife, 6¼"
These exceptional knives feature a unique 3-ply stainless-steel construction. The core or middle layer of VG-5 is very hard and acts as the cutting edge. The two outside layers are made of SUS410 stainless steel. This steel serves to protect the cutting edge and is softer and more stain resistant.
To appreciate the quality of the razor-sharp edge, first look at its incredible mirror polish and then cut with it. The edge on the knife is a minute, beveled edge at an angle between 14° and 15°, achieving the perfect balance between sharpness and strength.
This boning knife is balanced with a stainless-steel weight that attaches to the tang and is visible at the heel of the handle. The handsome handle is made of a rich, dark laminated wood. The handle shape is distinctive yet classic and fits very comfortably in the hand. It gives you the tradition and warmth of wood without an exposed metal tang that can sometimes cause discomfort.
Hand wash. Use any MinoSharp product to sharpen. Limited lifetime warranty. 6¼". Made in 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.
The SAN 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 design, it also creates fantastic balance.
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 handle is made of a rich, dark laminated wood. The handle shape is distinctive yet classic. The handle fits very comfortably in the hand. It gives you the tradition and warmth of wood without an exposed metal tang that can sometimes cause discomfort.
Care should be taken not to put the SAN knives in the dishwasher. For sharpening the SAN knives, any of the MinoSharp products will work fine. Made in Japan.
