Change Blade on Milwaukee Fastback 1901 Utility Knife

What happens here

Next, the video demonstrates changing the blade on an older model of the Milwaukee Fastback Utility Knife, specifically referred to as a '1901'. To change the blade, first fully extend the existing utility knife blade from the knife body. Once extended, locate the small, circular blade release button situated on the side of the blade carrier mechanism. Press this button firmly to disengage the blade. Carefully slide the old, dull blade out of its slot. Then, take a new utility knife blade and slide it into the exposed track of the blade carrier. Push it in until you hear and feel a click, indicating that the blade is securely locked into its operating position. Finally, retract the blade back into the knife for safety.
