With Melee 1 you must choose which type you are Specialised in.
Unarmed: Punching, kicking and wrestling; using improvised weapons in a bar brawl.
Blade: Attacking with swords, rapiers, blades and other edged weapons.
Bludgeon: Attacking with maces, clubs, staves and so on.
Given that you styled this as 'self defence' Unarmed might make sense, but your Noble upbringing might suggest Blade if you picked up and used a sword (and maybe you found your childhood fencing training helped?).
You get the other types at 0 as well, knowing some melee means you are not completely untrained in other forms.
