SAN MAI Tsubame Line:
The Tamahagane SAN MAI Tsubame knives feature a 3-layer stainless steel construction.
The middle layer is VG 5 which is very hard and acts as a cutting edge.
The outer two layers are made of SUS410 stainless steel which are softer and stronger than the cutting edge and really protect the cutting edge.
There are several VG stainless steels.
VG 5 stainless steel was selected for the SAN MAI Tsubame knives, as VG 5 can be hardened to the maximum capacity of other V-G steels, but has a top edge retention.
The angle of the sharpening is between 14 and 15 degrees.
The handle is made of fine Micarta which offers an impressive look and feel very similar to wood while being more durable.
Micarta is a pressed linen material that is infused with resin, creating a comfortable grip without the need for maintenance.
The blade is hand hammered down to about halfway.
The entire blade is then sandblasted.
Hardness of the blade HRC 58/59
