For naming all the machines on my home network, I go with the theme of "kinds knives or blades". I like the symbolism (knives are symbolic of logical thought).
The only problem is that I have a lot of machines, and am running out of names!
My fiancé runs a knife factory. There are so many names. Perhaps you just need to embrace some of the more descriptive names! “Folding Hunter Knife - Nickel Silver Drop Point”
That would be one way! But I also want the names to be relatively short and contain no spaces or non-alphanumeric characters, because I type them in a lot.
I still have 20 or so left on my "future names" list. I'm now into names of knife types in the African continent.
