Now don't jump all over me for this but, the reason that carbide and file sharpened edges are inferior is because the edges both tools produce are only superficial. Yes, they often feel frighteningly sharp and you may even be able to shave your arm with this type of edge but it is not nearly as durable as a honed and polished edge.
I know with broadheads we're looking for "one time" cutting performance but, what if a bone is hit on the entrance side? The blade is instantly and substantially dulled because the burr or straightened wire edge that is doing the actual cutting is very fragile and shears off on contact with anything remotely hard. Even penetrating the hide can often dramatically dull this type of edge. What's left is a dull underdeveloped edge that rips rather than slices the rest of the way through the animal. Tearing or sawing through tissue promotes clotting whereas clean slicing retards clotting.
Carbide sharpeners are fast, and require little skill to use, so they have their place for sure. Like Bill C. said they are great time savers but finishing on a stone will always result in a sharper, much more durable edge. The question is not how sharp are the broadheads in your quiver, it's how sharp is the broadhead after its done its job? If you can still shave your arm with it after it has passed through the animal, then there is no doubt that it sliced cleanly through every organ, vein, capillary in its path.
As for American broadheads being less sharpenable than the German made Silverflame... I have to disagree Joe. I have Grizzlys, Zwickys, Magnus and countless other broadheads that are every bit as sharp as the Silverflames. They will plow hair with the grain, across the grain, or against the grain. I have even seen a guy shave his face with a Zwicky Eskimo. Not a beard, just a couple days growth. (longer hair is much easier to shave than stubble). The Silverflames are without question great broadheads and they will hold an edge longer than just about any other broadhead but, our American broadheads can be made just as sharp or sharper.
