I don't think he was arguing that the size of the ingame sickle is unrealistic. You might wonder what the relevance of the hammer is in his pic...Nope - there was no set standard angle, length or curve to the blades, because each blacksmith had his own style.
and - as for sickles:
Yes, I realized it as soon as i started a fight. I could adjust an angle better to see the opponent more, but still vanilla max zoom for fights is perfect for awareness.Why, its terrible for fighting and most things haha. Novelty of it will wear off in minutes.
