[exsanguinate]

After 5 hours of hacksawing and filing, I finally got my knife cut out from ATS34 stock. I have Loveless/Barney's book on knife-making, but it really doesn't answer my question. My design changed a bit, but I need to know how I will work the file in order to get the shape of both edges and line in the middle of the blade. Do I file the bottom edge completely then work on the top? File one side (top and bottom) then work on the other? Do I taper file towards the tip of the blade then work on the edges?

Thanks in advance.
