A bit too big but it is pretty neat :D.
You should consider making the blade have a more sharp look at the edge, point, tip, looks pretty neat, however I’ll try making the blade (point) have a sharp type of design to it on the knife; since you have a decent model, but I’ll try placing the rivet on the handle, it’ll probably improve the whole design on it are you going for a kitchen knife?, If so I’ll try making other models instead of one example of other models it might help providing more feedback instead of a single build.
Correct me if i’m wrong but the tip is the end of the blade. Notice in the image below that the sharp “point” of the blade is has a sharper tip of it as yours doesn’t quite show that, although the point is, of course, part of the tip. I’ll try making the blade have a more unique shape as of right now the blade doesn’t look sharp from my point of view. And, yes, sometimes this area of the blade is useful for chopping or easy items. However, your knife looks pretty neat, I’ll try maybe placing a metal texture to the blade and see how it looks.
Overall it’s a decent model.
I think it looks really good, and the material makes it look like a real knife, but there is a line that kind of stands out a bit in the middle of it, if you could fix it and maybe make it a bit smaller(unless you’re going for a massive butcher knife) then it would look great 
This is very cute, but I agree, it’s a wee bit over-sized .
