When To Change a Replaceable Blade?

Utility blades last around two to three months on average. However, you might need to change your blade more often depending on how frequently you use it. Here are the most common signs that indicate it is time to switch out blades:

How To Change a Blade in a Utility Knife

Changing the blade on your utility knife handle is super easy! Here are 6 steps to ensure you switch blades safely and efficiently:

#1 Safety First

Before you replace or add any extra blades, there are some essential safety checks to do. Make sure you're wearing protective gear , including gloves, to prevent injury when handling new blades. You also need to check your utility knife is fully intact, with no signs of breakage or cracks on the handle.

#2 Locate and Press the Blade Release Button:

Find the blade release button on your utility knife (they are usually located on the side or top of the handle). Press and hold the blade release button to unlock the old blade. Keep your finger firmly pressed down on the release button until the blade is all the way out.

#3 Safely Dispose of the Old Blade:

Responsibly and safely throw away the used blade by placing it in a special disposal container or wrap it in heavy duty materials, like tape or thick paper. This will ensure the sharp edge is covered, so it doesn't injure anyone who handles the trash, or cause damage to receptacles

You should also check how the blade can be disposed of - can it be recycled or dropped at a hazardous waste center?

#4 Insert the New Blade:

Press down on the release button, just as you did when removing the blade, and slide your new blade into the slot until you hear a click. Once the blade is locked in, you can release the button. Double check for any movement of the blade - if you notice the blade wobbling or sliding about slightly, it means it's not properly inserted.

#5 Test the Blade:

Before you put your refurbished utility knife to work, double check it works properly. Gently swipe the blade along a material to make a few cuts and ensure all is up to standard. This will prevent any mishaps and ensure you can dive straight into tasks without any interruptions.

#6 Secure and Store:

If your utility knife has a retractable blade, be sure to fully retract it after testing the blade out. This will promote safety while protecting the fresh blade from damage. 

Ensure you store your utility knife safely in a designated space to prevent loss and accidents. Consider investing in a secure toolbox or organizer, such as the 16-piece Light-Duty Office Tool Kit by Great Neck , if you haven't got one already.
