FYI

Blademaster/Swordmaster only refers to the mastery of sword, .

this are two different things, blademaster is not just a mastery of the sword , it has an actual meaning and applied to games , a blademaster is adept in ALL melee weapons ,think of Bloodborne main character the Hunter, he's an actual blademaster because is adept in several weapons.
as for swordmaster in this yes , just master of swords.
