Disclaimer: This will be full of inaccurate stuff like naming examples and outrageous balance suggestions, It's just an attempt to "fix" katana.Here goes:
Add at least two more versions making it three in total, something like this:
"Ronin" Katana
"Samurai" Katana
"Kensai" Katana
Ronin Katana=Cheaper(6k?), slower(99-98 spd), less cut 36c?, heavier
Concept description:
Mass produced, low(-est) quality, repaired several times through its life time.
"Regular" Katana made for the battlefield
Samurai Katana=Same as original
Concept description:
Compromise between custom made and low price.
Duelists Katana
Kensai Katana= More expensive(15-20k?), lighter maybe even(1.2-1.3), faster 101 speed, "Cannot block", Thrust dmg=22p?
Concept description:
Custom made Masterpiece only fit for the best(and/or wealthiest) 2H Heroes.
Very thin, light, delicate... but still VERY deadly if wielded correctly
Cannot block motivation:

I'll say it one more time the Ronin, Samurai and Kensai prefix are just placeholders for better ideas that I'm sure is out there.
