I need help figuring out how to extrude/create this edge.

[Anonymous]

I am trying to create a double edged knife thing and I haven't been able to figure out how to create it to my liking. 

Some Details:

The whole thing is symmetrical I created the left side and mirrored it over the Y-Axis.   The inside arch is just a copy paste of the outside arch only moved in and trimmed.   The tip line is about .7 mm and the side line is about .35 mm. 

My hopes for the creation:

I want it to be flush with the middle part without cutting into it. I want it to follow the lines on the sketch and I want it to go from flat to a point. 

Sorry if it's not enough details I'll attach the fusion file. If it doesn't work like that sorry this is my first forum post.

Thanks for the help in advance. -Ryan

If you go through the timeline you should be able to see how I did this:

I'm just curious...

1. What are the separate little block bodies for?

2. What are the lines for that go out and touch the little block bodies?

3. They don't seem to define the desired edge (which I assume is defined by the blue lines) as the outside corner they make does NOT coincide with desired edge.

By the way, I get pretty much the same thing as @TrippyLighting , starting over from scratch, with just a single sketch. Extrude the middle (constant thickness) part, easily then build an edge with surface lofting/patching/stitching. Notice only a single sketch...

1. I created those little blocks as points to help me figure out where the edge is.

2. The lines are supposed to be the exact edge that I am looking for.

3. I thought that when I made them I made it on the edge by including the geometry and then creating a little box from it but i guess I messed up in some way.

Thank you for your help.
