As for katanas, i've only found this famous trope once(!) and never ever had a chance to actually use one. And looks like never will
BTW, my proposal - weapons can be grouped in 3 categoties: common, rare and unique.
Common are just that, in every game you should be able to find tons of this.
Rare are not as common
so you most likely find only 1-2-3 or even none at all. But this weapons must be a little (or not-so-little) better than previous category.
Unique - this is something new that I propose. Basically, it's one-of-a-kind weapon, most likely associated with certain unique (hence the name). Only way to get one of those is to kill whoever is carrying them.
For example weapons like triple sword, double sword and scythe (yeah, Sigmund should keep his signature weapon) make perfect candidates for this role. IMHO, they make little sense now as ordinary weapons (even rare). They don't nessesary has to be much better or stronger, but they difinitely will add some flavour to the game, and also will make uniques even more interesting when now. Also, this weapons will look cool in you YAVP log
So, here an example. "Remove" is mainly based on this page
