Please note that the scenario described below is a work in progress and subject to change. There is a point in one of my stories where a main character (wielding a knife- albeit a very long one made for combat) clashes with the main villain (wielding a hand-and-a-half sword). The sword-wielding combatant is older, being both a more skilled warrior, but also tiring more easily than the younger knife-wielder. After a fierce clash (in which the youngster is able to dash about more quickly and whittle away at his opponent), the veteran begins to tire of wielding the heavier weapon; he basically says "You really want to play it that way, then?", casting off his sword and reentering combat with a knife. How plausible is this? Admittedly, the villain is hellbent on killing his opponent and is getting fed up with this youngster's bull***t, but was he really that wise in abandoning the slower, yet farther-reaching, weapon? The kid was able to slip in close and attack him a few times with the knife anyway, so would it really matter which weapon the villain used to start with? *I wrote the scene this way for dramatic effect; the clash gets much quicker and more dangerous for the protagonist once the villain moves in with a knife. I'm just asking for outside opinion on the plausibility of this fight in general.
