That’s exactly what that highly trained 80 year old assassin wants you to think.
Her blade’s only sharpened on one side, and she’s well versed in close quarters techniques. She can spin with the tip held only inches away from her body, or do a short arc slice that’ll open you up like a side of beef.
I highly suspect that the outcome may have been quite different had said accidental sword cane carrier been in a different age group or GASP “of swarthy complexion”. (and I’m not even going to go to the “had she been wearing a hijab” place…)
