Sheer Will - my first choice. The blade just screams “getting the job done, no matter what” to me. Be it simple living tasks while camping with your kids or doing what’s necessary to defend your loved ones, your life, your nation, this blade exudes the quiet, stone-set determination of a man pushed too far. Its name should match.
If not that one, I came up with a few others, but I don't like them as much:
Sweeping Desire - gorgeous blade, reference to its style
Deadly Ambition - it does look wealthy in a certain sense, doesn’t it?
Honor and Duty \
a warrior’s ideals/reference to the Bushido code for this obviously Japanese-inspired blade
Honorable Death /
Debt Settler - self-explanatory.
Domestic Defender (relating back to the public defender..? I don’t like this one as much but if you do, great!)
