I've been experiencing the same issue. Its possible that if you've been using the blade for a long time it's been getting dull, especially if theres blood or rust built up on the edges. I'm currently experiencing this too so I'm hoping to replace it with a new one soon
edit: OH PFF i js reread it and saw it wasnt really a blade problem. if you can see the opening of your cut then its likely a gaping wound, which gaping wounds dont bleed very quickly at first, but they'e very heavy, unlike shallow cuts (talking from experience). If this is your first time experiencing gaping wounds then let me just let you know that theres nothing you should really worry about, as long as your taking care of it. The most that will happen is they'll take longer to heal and you'll get some scars out of it.
Conclusion, if you can see the opening of your cut then it's a gaping wound, and while gaping wounds do tend to bleed at a slower rate, they bleed a ton so be aware of that. Also most of my gaping wounds have turned into keloid scars. When this happens I reccomend putting vaseline on them every night (especially if they start itching or hurting).
