    Typically one knows to change the blade when one starts getting razor cuts. A dull blade raises the chances of getting razor cuts.

    If you notice the blades are dull or rusty, or if the moisture strip is worn out or peeling up. A single blade razor should only be used once or twice. Usually the more blades it has, the longer it will last. I use 6 blade disposable razors, but they’re cheap ones from the dollar store. They usually last me about a week.

    Most have a colored strip along the top ahead of the blades that tell you, like it'll start out orange or blue or whatever, but the more you use it, the lighter it gets, and when you go to shave and look down at it and see that it's become all white, you change it.

    Otherwise, you know by feel. You know what a new razor cartridge feels like, how it cuts the hair smoothly and easily without any pulling and without cutting you. When it gets dull, it stops cutting so well and starts pulling the hair a little ways before it finally cuts through. As the hair gets pulled, your skin around it lifts up, and if it lifts up high enough, another part of the blade ends up nicking that skin, slicing a bit of it right off. Then you bleed. That's how most shaving cuts happen, in fact, not because it's new and sharp but because it's gotten old and too dull to cut hair well, though still sharp enough to cut skin quite well. So if you don't have the color strip, go by how it feels. If it's pulling at your hairs instead of easily cutting through them like when it's new, then replace it, and if you don't, if for some reason your numb to when the razor is pulling hairs before cutting them, then you'll know you need to because you'll soon start getting more and more shaving cuts, which because shaving cuts bleed for so long, it's kind of hard to miss.
