Well, as far as I know it might be something like: Kuroi no Kenkaku OR Kurokenkaku (in any case in Japanese the word black is kuro in case of just stating a noun or kuroi when it is an adjective while the word kenkaku means swordsman, however Japanese can be somewhat tricky when combining words :P and this is my opinion of how black swordsman would be translated, hope this helps)
剣士 (kenshi) is the Japanese word for "swordsman", so to say "master of the blade", we can say "master swordsman" or "great swordsman" 優れた剣士 (sugureta kenshin) means "Excellent/Great Swordsman" 名人芸の剣士 (meijingei no kenshi) means "Masterful Swordsman" I think either of those would work to say "Master of the Blade".
