I love the 940, but some of them come from the factory with a poorly formed sharpening choil that does not clear the plunge grind. A subset of those, like mine shown below, come with a corresponding recurve from the factory. I extended the sharpening choil on this knife using a chainsaw sharpening bit in my dremel tool. I began the work using the dremel, but completed the shape using the bits by hand. Then I finished with a ceramic rod. I'm no blade smith, but I think it looks good. It also feels good knowing that I rescued the knife and gave it a sharpening future.
