Fighting defensively to tire out an opponent is not good general strategy.
Well, it works fine against the likes of Duras; that guy kept hacking against the supposedly unyielding metal of Worf's weapon like there was no tomorrow, making this a self-fulfilling prophesy...
I mean, Duras' sword clearly had little mass. So 1) it shouldn't have been able to pierce the opponent's blade or "blade" and 2) it should have been agile enough to get past that blade or "blade" with almost trivial ease; double fault for Duras! Yet Duras seemingly engaged in this duel solely out of a desire to do the honorable thing - so a bat'leth might be the perfect way to deal with idiots who live and therefore die by the honor code! Especially if the code requires said idiots to choose an inferior weapon and to employ an inferior tactic when they are at liberty to choose otherwise on both counts.
There
are historical precedents for trussing up for a fight of endurance, and winning through passivity. The partial armor of a generic
homme d'armes is functional protection for an active fighter, but the full armor of a real knight is there to allow the knight to ignore the activity of the opponent(s), to stand his ground with minimal physical effort, and to concentrate on delivering the superior blows of his long-reaching sword against any fool who tries to be active against the knight. It's actually a massive handicap in knight-to-knight fighting, but
that type of engagement is a rare occurrence outside ceremonies.
Passivity also protects the dug-in infantryman, the submarine, and the burly bar brawler being accosted by a skinny karateka, placing the active attacker at a disadvantage soon enough. It's a tactic that easily backfires, but
not if you can tell in advance what sort of tactics and weapons the enemy will be using. And the big point about Klingon bat'leth fighting is that it's all ceremonial, impractical... And highly predictable.
