How to Replace a Utility Knife Blade How to Replace a Utility Knife Blade
Replacing the blade of a utility knife is an easy job. There are two main types of utility blades, with snap off blades and simple blades. Each one usually comes with its own blade mechanism, so let’s see how to change it.
Step 1 – Getting the Old Blade Out
If you are dealing with a snap-off type of blade, then its holding mechanism is a small plastic bolt on the button that fits into a hole in the blade. Remove the bottom cover from the blade’s running track, pull out the button and the blade, and simply lift the blade of that bolt.
If it’s a regular blade, using the screwdriver unscrew the back part of the utility knife, and you should have access to the blade. The holding mechanism is about the same, and you may also find some spare blades inside the cover.
Step 2 – Putting the New Blade In
To get the new blade into place, simply reverse the steps above. For snap-off blades, fix the blade onto the bolt of the button, than slide it in, and for the other type, simply put it in place and place the button to hold it. Push the bottom cover into place, or place the back cover and screw it, and you’re done.
