All of them, skill level has no effect on this:
Give 30% base Atk and 45% base HP to all weapons of the same type

Only active with 5 OTHER weapons of the same type, skill level buffs this:
Sword: Double(++)/Triple(++)
Glaive: Assault(++)/Triple(++)
Lance: Assault(++)/HP(++)
Axe: Exceed(++)/Ability(++)
Staff: HP(++)/Heal(++)
Hammer: Assault(+++)
Gun: HP(+++)
Bow: Assault(++)/Crit(++)
Arcane: HP(++)/Vigor(++)

The bolded ones are EXTREMELY good if you can activate the skill. The rest... are... questionable. Can certainly be worth it, but please know what you're doing.
