Proper Care
Guiding Tips
for Your New Cutlery Care
for a Lifetime of Precision & Performance Crafted for a lifetime
Our knives are easy to care for.
A few tips & and tricks ensure they stay razor-sharp.
  • Hand wash your knife immediately after use and ensure thorough drying.
  • Avoid using a dishwasher to prevent potential damage to high-carbon steel and handles.
  • Never leave the knife submerged in water for an extended period.
  • Sharpen the blade as needed using a quality sharpening rod (diamond or ceramic), whetstone, or similar tool.

How to Clean Your Knives?

  • Clean your knives promptly after use to prevent food particles or stains from solidifying & becoming difficult to remove, which could dull the blade.
  • Stick to hand-washing, especially for high-quality k nives.
  • When hand-washing, keep the blade pointed away from you, and use a dishcloth or sponge with warm water and dish soap to carefully wipe each side of the blade. Lay the knife on the counter for added caution.
  • Always use the honing steel to realign the edge before or after use, and sharpen the knives as needed; Use a quality cutting board. We highly recommend using bamboo or wood cutting boards. 
  • Never leave the knife submerged in water for an extended period.
  • Avoid aggressive scrubbing to prevent accidental cuts; soaking is usually sufficient to loosen particles for easy removal.
  • For stubborn particles, soak the knife for a few minutes in a mixture of hot water and dish soap.
  • After cleaning, carefully wipe the blade dry to prevent water marks.
  • For wooden-handled knives, treat them regularly with linseed oil or beeswax to prevent brittleness. This provides effective protection and enhances the wood with a silky sheen and rich color.
  • If the knife has some signs of rust (which might happen if left in water or if you use a dishwasher), please use Bars Keepers Friend™ Stainless Steel Polish (or similar) to clean your knife ASAP once the rust is removed. make sure you hand wash and dry the knife after use.
  • Avoid glass, ceramic, and plastic cutting boards as they will dull your knives quickly.
  • Avoid using a dishwasher to prevent potential damage to high-carbon steel and handles.

How to Sharpen Your Knives?

  • Gather a sharpening stone or a user-friendly knife sharpener.
  • Inspect your knife for any damage or irregularities. Wipe it clean with a damp cloth.
  • Maintain a consistent angle, around 15-20 degrees, while sharpening. This ensures a proper edge.
  • If using a sharpening stone, start with the coarse side, then move to the fine side. For electric sharpeners, follow the device's instructions.
  • Safely test the sharpness by making a few cuts. Once satisfied, store your newly sharpened knife in a secure place.

What Is the Ideal Knife Sharpness?

Knife Sharpness and Blade Angle:

Generally, the sharpness of a knife is influenced by the angle of the blade. more acute angle results in a sharper blade. The ideal degree for a knife typically falls between 15 and 30 degrees.

Knife Usage and Storage Tips
