What are the disadvantages of a katana?

As an expert in finance and cryptocurrency, I'm not typically delving into the intricacies of Japanese swordsmanship, but I'm curious to understand the other side of the coin. So, might I inquire about the potential drawbacks of wielding a katana? Are there any inherent limitations or disadvantages that one should be aware of when considering this iconic weapon? Could its weight, length, or maintenance requirements pose a challenge for some practitioners? Or are there other factors that might influence one's decision to choose a different sword?
