Re: Explanation for the blade of qutluch?
I suspect if I told an alien I'm getting a "knife" there are any number of examples I could use. I could use a butter knife one day, a swiss army pocket knife the next or a machete the day after. All of them I'd still use the word "knife" to describe. I would assume the Klingons would have more than one type of "Qutluch" too.
