How to prevent a wooden knife from cracking?

Jul 16, 2025

Hey there! I'm a supplier of wooden knives, and I know how frustrating it can be when these beautiful pieces start to crack. Wooden knives are not only functional but also add a touch of natural elegance to any kitchen. In this blog, I'll share some tips on how to prevent your wooden knives from cracking, so you can keep them in top-notch condition for years to come.

Understanding Why Wooden Knives Crack

Before we dive into the prevention methods, it's important to understand why wooden knives crack in the first place. Wood is a natural material, and it reacts to changes in its environment. The main factors that can cause wooden knives to crack are:

  • Moisture: Wood absorbs and releases moisture depending on the humidity of the surrounding air. If the wood absorbs too much moisture, it can swell, and when it dries out quickly, it can shrink and crack.
  • Temperature: Extreme temperature changes can also cause the wood to expand and contract rapidly, leading to cracks.
  • Physical Stress: Using the knife for tasks it's not designed for, or applying too much pressure during cutting, can cause the wood to crack.

Proper Cleaning and Drying

One of the most important steps in preventing wooden knives from cracking is proper cleaning and drying. Here's how you can do it:

  • Hand Wash Only: Avoid putting your wooden knives in the dishwasher. The high heat, strong detergents, and rapid water movement in the dishwasher can cause the wood to dry out too quickly and crack. Instead, wash your wooden knives by hand with mild dish soap and warm water.
  • Use a Soft Sponge or Cloth: When cleaning your wooden knife, use a soft sponge or cloth to avoid scratching the wood. Gently scrub the knife to remove any food particles or stains.
  • Dry Immediately: After washing, dry the knife thoroughly with a clean towel. Make sure to remove all the moisture from the wood, especially in the handle. You can also let the knife air dry for a few minutes before storing it.

Oil Your Wooden Knife Regularly

Oiling your wooden knife is an excellent way to keep the wood hydrated and prevent it from drying out and cracking. Here's how you can do it:

  • Choose the Right Oil: Use a food-safe oil, such as mineral oil, coconut oil, or beeswax. These oils are safe to use on kitchen utensils and will help protect the wood.
  • Apply the Oil: Pour a small amount of oil onto a clean cloth and rub it into the wood in a circular motion. Make sure to cover the entire handle, including the edges and crevices.
  • Let it Soak In: Let the oil soak into the wood for at least 15-20 minutes. You can then wipe off any excess oil with a clean cloth.
  • Repeat Regularly: Depending on how often you use your wooden knife, you should oil it every few weeks or months. This will help keep the wood in good condition and prevent cracking.

Store Your Wooden Knife Properly

Proper storage is also crucial in preventing wooden knives from cracking. Here are some tips on how to store your wooden knife:

  • Keep it in a Dry Place: Store your wooden knife in a dry place, away from direct sunlight and moisture. A knife block or a drawer is a good option. Make sure the storage area is well-ventilated to prevent the wood from getting too humid.
  • Avoid Stacking: Don't stack other items on top of your wooden knife, as this can cause physical stress and lead to cracks. If you need to store multiple knives, make sure they are separated and have enough space.
  • Use a Protective Sheath: If you're transporting your wooden knife, use a protective sheath to prevent it from getting damaged. This will also help protect the wood from scratches and other physical stress.

Be Gentle with Your Wooden Knife

Finally, being gentle with your wooden knife is essential in preventing it from cracking. Here are some tips on how to use your wooden knife properly:

  • Use the Right Cutting Surface: Always use a cutting board made of a soft material, such as wood or plastic. Avoid using hard surfaces, such as glass or granite, as these can cause the blade to dull and the wood to crack.
  • Don't Overload the Knife: Use your wooden knife for tasks it's designed for. Don't try to cut through hard or tough materials, such as bones or frozen food, as this can cause the wood to crack.
  • Sharpen the Blade Regularly: A dull blade can cause the wood to crack more easily, as you'll need to apply more pressure when cutting. Make sure to sharpen the blade regularly to keep it in good condition.

Other Tips and Tricks

Here are some other tips and tricks that can help prevent your wooden knives from cracking:

  • Avoid Extreme Temperatures: Don't leave your wooden knife in a hot car or near a heat source, such as a stove or fireplace. Extreme temperatures can cause the wood to expand and contract rapidly, leading to cracks.
  • Check for Signs of Damage: Regularly inspect your wooden knife for signs of damage, such as cracks, splinters, or loose handles. If you notice any damage, stop using the knife immediately and take appropriate action.
  • Invest in Quality Knives: When buying wooden knives, invest in high-quality knives made from good-quality wood. These knives are less likely to crack and will last longer.
