I got several blades from my junk drawer and started to grind and shape. Here are the first 5. I have them hanging right now with the liquid handle coating the end to make them safe to hold.
The hardest one obviously was the .010, but I started with a .025 hacksaw blade, and ground a little at a time and checked often. I used a table belt sander.
Here is a photo of the ground down blades.
