It looks no more or less effective for SD as any other folding knife. Or grocery store steak knife. Or screwdriver. Or broken bottle. Though it does has writing on the blade, which does make it better for self-defense.
For edc, one can do way better for the price. The handle shape is silly at best, and it appears to be a hollow saber grind, which, in my opinion, is less than ideal for the kind of "general, all around" tasks an EDC is asked to do.
I'd suggest something with a full flat grind that actually cuts things as an EDC knife (Opinel, SAK, etc) and let situational awareness and running away be your self-defense tools.
Or just get a Delica or Griptilian. Those are always good choices.
