In Klingon people use phasers and it feels like it should only mean
phasers--- Marc Okrand has a word for potato gun-I'm sure of it, he just
hasn't announced it. So it will feel odd to use these super specific words
as general category words.

Having met Okrand, I wouldn't doubt that at all.  He seems the sort who
might keep a potato gun handy for when things get dull.
