There are different skill levels for sharpening knives. People on the low end want a sharp knife from the factory because it's better than what they can yield. I think this is the group paratrooper is speaking for. I mean no disrespect - sharpening knives well is a skill one must obtain through dedication, the right tools, ect.
I incorrectly lumped all the people who sharpen knives to have the high skill level many users on this forum have in attaining a perfect edge. Paratrooper has a valid point to oppose one of my previous posts here.
