Wiki-Zenkou(All Steel)

Full Steel (Zenko) is a type of knife construction where the entire blade is made from a single piece of metal. Below is a detailed explanation of the features, benefits, and considerations of full steel knives.

Features of Full Steel Knives

  • Single Material:
    Full steel knives are made from a single piece of metal, with no separate layers for the core and outer parts. This results in a uniform hardness throughout the blade, offering high durability and sharpness.
  • Flexible Sharpening:
    Unlike double-beveled knives, full steel knives can be sharpened in a more flexible manner. You do not necessarily need to sharpen both sides equally, which allows for a "single bevel-like" sharpening technique. This gives users more freedom to sharpen the knife according to their preference.

Benefits of Full Steel Knives

  • Excellent Sharpness:
    Knives made from full steel are known for their high hardness and sharpness, allowing for smooth cutting of ingredients. They are particularly effective when handling meat or fish.
  • Durability:
    Because they are made from a single piece of metal, full steel knives are less likely to chip or crack, providing long-term durability.
  • Maintenance:
    Full steel knives are relatively easy to sharpen and maintain. Regular sharpening ensures that the knife retains its sharpness and performance.

Considerations for Full Steel Knives

  • Prone to Rust:
    Full steel knives are often made from high-carbon steel, which makes them susceptible to rust from moisture and acids. It is essential to wipe the blade dry after use and store it properly to prevent rusting.
  • Price Range:
    High-quality full steel knives are generally expensive, but their performance and durability make them a worthwhile investment.
  • Handling:
    Since the blade is hard, applying excessive force can cause chipping. Caution is needed when cutting hard materials like bones.

Summary

Full steel knives are highly favored by chefs and enthusiasts for their excellent sharpness and durability. With proper maintenance, they can provide outstanding performance over time. They are a valuable tool for expanding your culinary repertoire and can be a great addition to any kitchen.
