are long weapon versus either short weapon or double short weapons. For example, with pu dao versus saber what we really have is a contest between two saber blades with speed and perhaps a little more precision on the part of the saber and reach and probably slightly more hitting power on the part of the pu dao. There would be the question of whether the juncture where the pu dao blade joins the staff holds up as well. Can the staff of the pu dao successfully block a saber cut? There’s the additional consideration that the lower end of the pu dao can also deliver a strike as well as a block. I have never seen a weapon that we might describe as a double-headed pu dao – a saber blade on each end. It is also possible to enhance the staff section of the pu dao with crescent moon guards or spikes that could not only serve to deflect slashes (presumably aimed at a hand or maybe just the staff/handle itself) but could also be dangerous – we hope for the opponent only – during close encounters. As before, adding the weight for guards and spikes is trading some speed and flexibility for tactical advantages. Hybrid weapons like the horse-blocking knife and the sun-moon swords add the crescent moons, but I have never heard of a pu dao, which would have a longer, heavier blade, with such additions.
When the opponent has double short weapons the tactical situation for the pu dao wielder is not so simple: just bashing aside the enemy blade and lunging in is very likely to encounter enemy blade number 2. This means preference should be given to beating aside the enemy’s right hand blade (for example) NOT outside to the enemy’s right and your left, but rather the other direction.
There’s not much effort put into long weapons blade or head design in terms of seeking to entangle (and presumably wrench away or snap) an enemy blade.
