These axes are designed explicitly as weapons, rather than tools. They typically weigh less, with a shaft reinforced with metal bands or bolts, and have a sharper blade, making them ideal for chopping limbs rather than wood.
Traits
Sweep: This weapon makes wide sweeping or spinning attacks, making it easier to attack multiple enemies. When you attack with this weapon, you gain a +1 circumstance bonus to your attack roll if you already attempted to attack a different target this turn using this weapon.
Critical Specialization Effects
Source Core Rulebook pg. 283 4.0Certain feats, class features, weapon runes, and other effects can grant you additional benefits when you make a Strike with certain weapons and get a critical success. This is called a critical specialization effect. The exact effect depends on which weapon group your weapon belongs to, as listed below. You can always decide not to add the critical specialization effect of your weapon.
Axe: Choose one creature adjacent to the initial target and within reach. If its AC is lower than your attack roll result for the critical hit, you deal damage to that creature equal to the result of the weapon damage die you rolled (including extra dice for its
striking rune, if any). This amount isn't doubled, and no bonuses or other additional dice apply to this damage.
