Help with design error

Second time posting this, i've been trying to make a knife by following a guide on youtube, I've come to a part where i need to make a sweep on the blade and when i do so i get an error saying the body would intersect itself. I followed the guide by doing the same things he did yet i get an error while he didn't.

You profile sketch for the Sweep is too long and it will intersect itself at the beginning of the sweep. You will probably be mirroring this sweep to form the other side of the blade so the sketch only has to include a little over half the knife blade thickness. Model is attached.

It would be useful to include the link to the YouTube video so that it can be demonstrated where your attempt is different.
