Suggestion for making a low poly from my high poly axe

maxivz

Hello guys
Well, after spending some time playing skyrim i have decided to make an axe, so i made this crappy axe model
The problem is that this is the first time i have ever scupulted some detail in a model and i am wondering what would be the best way to make the low poly, i have tried max optimize modifier but it destroys a lot the silouete of the model
What would you recomend me doing?

the forms are basically a cylinder and a rectangular prism, you could easily just model around it pretty quick. you could also use retopo tools, but for something like this you don't even have to, really
