 | SAN Tamahagane Knives
MATERIAL 3 layers of VG5 (core) and SUS410 (outside layers) MANUFACTURING METHOD The blade material of 3 layers with the original thickness of 20mm has been thinned to the final thickness of 2mm by rolling processes repeatedly applied. In other words, 3 different materials have been compressed in 2mm. HARDNESS After the rolling processes, the material of VG5 becomes harder and harder to be 58-59 degrees Rockwell hardness in the final thickness of 0.65mm. Meanwhile, the two outside layers of SUS410 will remain at 28-32 degrees Rockwell hardness to strengthen the blade and protect against damage and corrosion. SHARPNESS This is the outstanding feature of the knife. The blade is sharper and remains sharper longer than normal knives. RE-SHARPENING Easy grinding because of very thin VG5 with softer SUS410 on both sides. The sharpening angle is 28-30 degrees. HANDLE Distinguished in corrosion resistance making use of compressed laminated wood.
