>>270701This is like the complete opposite.
The flat serrations you usually find on a knife are designed to provide a sharpened edge that's 2 to 4 times longer on the same length, and with a sawing movement, and the cutting angle can vary to as much as 70°. So yes, it HAS to cut better.
It has nothing to do with protecting the blade edge from hard surfaces, they're simply designed to maximize cutting efficiency on relatively soft materials, but aren't fit for cutting hard materials because the serrations are smaller than the blade, and thus even if they do cut into the hard material, it'll only lead to the blade getting stuck. Hence why wood saws have serrations at least as large as the blade, which sometimes has a triangular shape, so that they can cut a path large enough for the blade to get through, when flat serrations can cut any material that can allow a blade larger than its serrations to pass through.
