I've owned both Spydercos as wellas Kershaws. Sometimes the steel of the Kershaw was actually superior to that of the Spyderco but for some reason the Spydercos seem to be way more sharp than the Kershaws. Is this because of the way the blade is grinded, or is it just that Kershaws aren't that well sharpened out of the box? Is there any way to sharpen the Kershaws to make them as sharp or even sharper than the Spydercos, or does the difference in blade design just not make it possible?
