also if you filed your blades down to the point where they are almost sharpened like ray said dull the edge...however on your next one don't file them as much leave the edge at about the thickness of a dime then after heat treat (and generally the last thing that gets done) put a secondary bevel on that edge that is the thickness of the dime and sharpen that ....it prevents warping I heat treat all my blades before I grind bevels on but you cant do that if your working by hand however I have seen pics of people that made the edge too thin and during heat treat it can warp the worst I saw a pic of the edge was grinded almost done and it looked like a piece of bacon (very wavy) when it came back from heat treat
