CUTTER FLUTES, HOW WOULD YOU MODEL THIS

O.K. Fellow solidworks gurus, I am actually stumped on this one. Ive done several cutters in solidworks, with flutes. This one has me stumped. I would really appretiate if someone can download my files and give me some advice on how this can be accomplished.

This cutter will be made in 3 sizes, small medium and large. each being about .25% larger than the next. The one I have uploaded is the small.

This one was done using surfaces (As an experiment) and is so far, unsuccsessfull as I cannot get the last surface to work.

I have tried this using solid tools, such as sweep cut, and loft cut.

It is clear what I need, as I have uploaded jpegs of the actual part.

PLEASE HELP!!!

P.S., If someone can resolve this for me, (tell me how its done) I would gladly mail you a case of fine beer

To all of you who were kind enough to offer your help, I though it would be nice to upload my new file to show how I solved this issue. As it turns out, I was over thinking this. It turned out to be much simpler than I had thought. Look at the file called cutter, burr if interested. I would love to hear comments on this.
