Any chance that blade has an elephant stamped on it? If so, the blades themselves are not square. I talked to Bruce about one that I had in for sharpening last winter. the blade edge had been ground properly and was next to new...problem I found was over 3/16" in depth (front to back) from blade end to blade end. The blade was also not equal in thickness. Needless to say, I spent a lot of hours truing up this blade. Customer is still elated with it, but man I lost money on that deal
