I am a very loyal Benchmade customer and have many of their knives. I recently bought the 810 Contego and noticed the sharp edge on the blade is very uneven. There is very little edge on the bottom of the blade, but a lot of edge near the belly/ curve of the blade, and then less of an edge near the tip. Also, one side of the blade is sharpened at a different angle of the other side of the blade. Is this normal or grounds for using the warranty work? All of my other Benchmades have perfect edges on them. Thanks for you help.
