/cgl/ - Cosplay & EGL

Hey guys -

I'm a complete noob to cosplay (and working with my hands, really), and my first project is Guts from Berserk. I have access to a shop and some power tools, so I (with help, of course) was able to cut a tapered, straight edge blade with a table saw, as you can see in this album (hand for scale):

However, I need help cutting the very tip of the blade. That edge does not stay constant throughout the whole sword, and instead changes angle at the tip of the sword. Any suggestions on how would I make it so that the sword does this?

Thank you! Again, I'm a total noob to this so what may be an obvious answer isnt so obvious to me haha
