I think a change of method.
I would use mirror at end - this will simplify the sweep cut.
The path for sweep need to change to get the curve at blunt end.
For your sweep - try to sketch the profile "normal" to the path, rather than at an angle.

I would only use the right profile. Make a spline for your profile to follow by using the convert entities ( you may need to extend it past the tip of the blade). If you upload your current file I can play around with it and give you a tutorial.

Here the file. I tried only with the right part but its not proportional.

Sorry i have forgot for different versions. Here
