You think the people who made the grim reaper blades are stupid????

I'm sure they divised countless experiments until they found the perfect one where their blades outperformed all others by a land slide. Objective evidence does not come in the form of advertising...consider that when you're watching all commercials!

That said...any broadhead will kill a deer, and perhaps a steel drum. It's just a matter of what aspects of performance you prioritize above others
