Weapon discussion/questions

Hey there guys, I’m new to ZBrush and I looked throughout the forums and can’t find anything on weapons. It’s possible I was looking in the wrong spot so if I need to put this somewhere else let me know.

Now to what I’m trying to do. I’m looking to make a scythe more or less. Now making the handle is simple since it’s just a long cylinder but the blade is what I’m having trouble with. I was thinking using a rectangle and masking off little sections at a time then rotating. Is there a better way to do this that will yield a better looking blade? Any help is appreciated!
