"you cant" Silly... Yes you can! Totally and easily! If this is the knife I have, there is a button in the middle of the handle that pops open the blade storage compartment. On the same side near the front end, there is another red button. When pressed, it doesn't even feel like it moves much. Look at a blade; see that there are 2 notches in the top? There is a little piece of metal that holds the blade in the knife. This is the button that disengages that little nubbin. To change the blade, extend the blade to its most forward position. Then press that red button, grab the blade (a pliers is safer than your fingers) and pull the blade out the tip of the knife. To insert the blade just do this in reverse. Be sure that the blade is, in fact, engaged and held securely before using the knife. Be sure to dispose of your blade safely. I wrap mine in duct tape and trash it.
