I decided to try mocking up some scales on my computer (using photoshop).

I scanned in my scaleless blades and a scale to use as a base for the template. I then pathed out the scanned scale so I had something to work with. Next I took my template and put it over the picture of the blade and started fiddling around until I got everything to a size that looked good.

Anyway, you can checkout the mock up I've created over here. Let me know what you guys think and if everything looks alright.
All I need to do now is print out the template and use it, but I wanted to post it here first to see if you guys catch any glaring errors I managed to make but overlook.
