Box cutters are essential tools for various tasks, such as opening packages, cutting through cardboard, or even for arts and crafts projects. One popular and trusted brand for box cutters is Westcott. If you own a Westcott box cutter and need to change the blade, this article will guide you through the process step by step.

Step 1: Ensure Safety

Prior to changing the blade, it is crucial to prioritize your safety. Make sure you are in a well-lit area and wear protective gloves to avoid any accidents or injuries.

Step 2: Retract the Blade

Start by retracting the blade fully into the handle of the box cutter. This step is essential to prevent any accidental cuts during the blade replacement process.

Step 3: Locate the Blade Release Button

Next, inspect the box cutter for a blade release button. This button is usually located on the side or top of the handle. Once you find it, press and hold it down to release the old blade.

Step 4: Remove the Old Blade

While keeping the blade release button pressed, carefully slide out the old blade from the front of the box cutter. Be cautious during this step to prevent any injuries.

Step 5: Dispose of the Old Blade Safely

Now that you have removed the old blade, handle it with care to avoid any accidental cuts. Place it in a puncture-resistant container or wrap it in multiple layers of newspaper before disposing of it in a designated sharps container.

Step 6: Prepare the New Blade

Unwrap the new blade from its packaging, ensuring you do not touch the sharp edges. Take a moment to inspect the new blade for any defects or damage before proceeding.

Step 7: Insert the New Blade

Hold the new blade carefully by the sides and insert it into the blade slot at the front of the box cutter. Push it in until you hear a click, indicating that the blade is securely in place.

Step 8: Release the Blade Release Button

Once the new blade is inserted, release the blade release button. This will lock the blade in its position, ready for use.

Step 9: Test the Blade

Before using the box cutter, test the new blade by retracting and extending it a few times. Ensure that it moves smoothly and securely in and out of the handle.

Step 10: Store the Box Cutter Safely

After confirming that the new blade is working properly, store your Westcott box cutter in a safe place away from the reach of children or pets.


Changing the blade on a Westcott box cutter is a simple process that can be done quickly and safely. By following these steps, you can ensure that your box cutter remains in optimal condition, ready to tackle any cutting task that comes your way.
