3D Printing?

Hi I am planning on 3D printing something and was wondering about some things:

1) What kind of programs can I use?
2) How hard would it be to create in the program/how much experience would I need? It's a pretty complex design and I have never touched 3D printing so this is unfamiliar territory. 
3)What are some good sites that will print this design from ABS plastic for cheap?
4) How well would I have to know my math? 
5) Is there anything else I need to know before I dive right in?

With this knowledge in mind I'd like for you guys to see what I plan on making
I really want this made and I would be the happiest man on earth if I could get it. Please help!

3D printing would be fine for some of the parts. You are going to need dimensions or spend some time with a ruler scaling the drawings. There are lots of things to take into consideration when modeling for 3D printing and those things change based on the method used. Honestly I would but this on the back burner for awhile, go get a 3D CAD program, autodesk offers 123D for free, and learn it. Once you are comfortable then get back into this project.

You should take people offering advice seriously. @rickharris is right, you should build a cardboard or balsa wood mock up so that you can fully understand how it works and goes together. Also you will be able to tweak the size until it is just right. This will help you when you go to model it on the computer as you will fully understand the shape of each piece.

As far as the actual printing the company Autodesk uses starts at $1.61/cm^3.

To be honest I wouldn't go 3D printing at all.

I would build it up out of thin material layer on layer where it needs to be deeper it shouldn't be a real problem at all.

At a minimum you should have made a full sized model before you do anything else so a) you know it works
b) You know the size is correct
d) you have something to show the company you pick to do the 3D work

Note in general it isn't cheap to get a one off made.

The problem with that is that I have no workshop to do that kind of stuff. I don't have ANY type of machinery to work with. Someone has already made something like this and it does work. I just don't have the resources to make this where I currently live.
Get a local engineering company to make one. Do ou just want one or need it for a purpose. You could make a cardboard mock up on the kitchen table with little more than a knife and ruler.

well I both want one and I need it for a costume. And if I wanted one from cardboard I wouldn't be asking this question.
Ok you need to find a company that will 3D print it and ask them what format the file needs to be in and go from there.

This isn't going to be cheap.

The seventh person you show it to will have you arrested ;-(

okay 1) I'm not stupid, I'm 16 and fully know about the laws of knives and sharp objects as well as concealment 2) Why would it be the 7th? 3) This is only going to be used as a prop, not an actual weapon. Again, refer to 1
