I used to wait waaay to long between changing my blades. That stopped when I ended up stabbing myself in the finger because I was pressing so hard because of the dull blade and the knife slipped.
Now I change my blade anytime I find myself pressing harder, or need to make more than two passes. Sometimes I just throw in a new one when I’m starting a project for someone else as stuff tends to come out nicer with a sharp blade.
+1 to the other user that mention stroping as that can help extend the usable lifetime (by a little).
But yeah, if you can get a big pack of them cheap online and just change them as you feel you need to.
