I'm working on my own version of the Dinobot swords, but can't quite figure out how to make the blade in the right shape:


The Object Wedge will create the right shape viewed from the front, but I can't work out how to put a sharpish blade edge on the sides of the wedge.

If anyone knows how to create this kind of object, can they explain how I might do it?

I am using FreeCad.
