Takefu VG-10

Takefu VG-10 steel, developed by Takefu Special Steel Co., is one of the most popular Japanese stainless steels used in kitchen knives. Its composition includes Carbon (C): 0.95-1.05%, Chromium (Cr): 14.50-15.50%, Molybdenum (Mo): 0.90-1.20%, Vanadium (V): 0.10-0.30%, Cobalt (Co): 1.30-1.50%, Manganese (Mn): 0.50%, and Phosphorus (P): 0.03%.

Note: All knife steels contain carbon, which is primarily responsible for hardness and edge retention. However, higher carbon content alone can reduce toughness. A steel becomes "stainless" when it has at least 13% chromium content.

When comparing VG-10 to other popular stainless steels:

  • SG2: A powdered metallurgy steel with a higher carbon content (1.25-1.45%) and higher levels of vanadium and molybdenum, providing superior wear resistance and edge retention compared to VG-10.
  • Ginsan (Silver #3): Similar carbon content (0.95-1.10%) to VG-10 but is easier to sharpen, resembling carbon steel while maintaining corrosion resistance.

Some users claim VG-10 is challenging to sharpen, though this often stems from limited experience with specific knife brands. While VG-10 may not be the easiest stainless steel to sharpen compared to Ginsan, it still offers a well-balanced performance.

Reminder: When selecting a knife steel for your Japanese kitchen knife, it's essential to understand that there are trade-offs involved. Improving one characteristic, such as edge retention, often means compromising on another, like toughness. There is no universally "best" steel; the choice depends entirely on your individual needs and preferences. Remember, steel is just one piece of the puzzle. Consider other aspects that matter to you such as the grind, aesthetics, and overall craftsmanship. While steel matters, it's not the only thing that makes a great knife.
