VG1 is a high-quality stainless steel that is known for its toughness and durability. It is also very resistant to corrosion and rust, which makes it an excellent choice for kitchen knives. VG1 steel contains approximately 0.95% carbon and around 14-15% chromium.
VG10, on the other hand, is a premium-grade steel that is known for its exceptional sharpness and edge retention. It contains higher levels of carbon (around 1%) and chromium (around 15%) than VG1, which gives it superior hardness and wear resistance. VG10 is also more expensive than VG1 due to its higher quality.
In summary, VG1 is a high-quality stainless steel that is tough, durable, and corrosion-resistant, while VG10 is a premium-grade steel that offers exceptional sharpness, edge retention, and wear resistance. Both types of steel are excellent choices for Japanese chef knives, but VG10 is generally considered to be the superior option due to its higher quality and performance.
