The bastard sword, lance, and dwarven waraxe are all two-handed weapons that can be used in one hand under the correct circumstances (the bastard sword and dwarven waraxe are shown on Table 7–5 as one-handed exotic weapons, but they’re really two-handed weapons). Treat all three of these weapons as two-handed weapons when determining who can use them and how. For example, a Small character cannot use a lance or bastard sword made for a Medium creature, even when mounted (in the case of a lance) or when the Small character has the Exotic Weapon Proficiency (bastard sword) feat.
来自faq。重剑本身是双手军武，拿专长后允许单手握持，作为一定环境下的特殊握法。
而看进阶条件的时候显然不考虑握法只考虑武器本身是啥武器吧？
至于只说了核心武器，我猜是这条faq比较早？虽然不知道怎么查一条faq啥时候出的，没依据。。。其他类似物也一样判就没问题了？
