• Why Kitchen Knives Become Dull

  • OCT4, 2024

  • The Cutting Board: Your Knife's Hidden Enemy

  • We use kitchen knives daily, but have you ever wondered why they seem to lose their edge so quickly? The truth is, the biggest culprit behind dull knives might surprise you - it's closer to home than you think.

  • The main reason knives become dull is that the blade edge becomes rounded. Surprisingly, this damage isn't primarily caused by cutting food, but rather by the impact with the cutting board.

  • The Impact Factor: What the Numbers Tell Us

  • Research has revealed some fascinating facts:

    • You can peel a daikon radish 10,000 times with minimal blade damage
    • Just 400 chops against a cutting board can significantly dull your knife

    This explains why kitchen tools that don't use cutting boards (like peelers and slicers) tend to stay sharp longer.

  • Daily Habits That Dull Your Knives

  • Common practices that damage your knife's edge:

    1. Using the blade to scrape food off the cutting board
    2. Sliding the blade sideways across the cutting board
    3. Cutting frozen foods

  • Choosing the Right Cutting Board

  • Your choice of cutting board can significantly affect your knife's lifespan:

    • Recommended: Soft wood materials like ginkgo wood
    • Avoid: Hard wood, Glass or metal surfaces

  • The Importance of Proper Maintenance

  • To maintain your knife's sharpness:

    1. Use a whetstone and sharpen until you achieve a proper burr
    2. Honing steels and roll sharpeners are temporary solutions
    3. Regular, proper sharpening is essential

  • Tips for Preserving Sharpness

  • Recommended Cutting Technique:　Use a sliding motion when cutting

  • Technique to Avoid:　Chopping with a repetitive up-and-down motion

  • Conclusion

  • Maintaining a sharp knife requires proper usage and care. By minimizing impact with the cutting board and implementing appropriate maintenance, you can ensure a more enjoyable cooking experience. Small daily habits can make a big difference in extending the life of your kitchen knives.
