What would be the Russian equivalent of "When All You Have Is A Hammer, Everything Looks Like A Nail", or an idiom of a similar sentiment?
Edit: This idiom means that if you only have one tool, you will use it for everything, even if it is not the right tool for the job.
I think you can use a literal translation, e.g. (from https://ru.citaty.net/tsitaty/655283-abrakham-maslou-avraam-maslov-ia-predpolagaiu-chto-esli-edinstvennyi-instrument-k/):
The meaning is pretty understandable, and such phrases are actually used (in different forms), e.g. example 1, example 2 (these are the result of some random googling). I actually remember seeing this phrase "in the wild" in some Russian texts before.
Moreover, the English phrase is attributed to either Abraham Maslow or Mark Twain, so it's not exactly an idiom. For a quote by some famous person, it is absolutely ok to use a literal translation.
A somewhat similar (albeit not entirely accurate in meaning) expression, "Стрелять по воробьям из пушки" (shooting sparrows with a cannon), means using unreasonably large resources to solve a small task.
Basically, what the English idiom says is that when you're viewing the world from a particular angle, you're inclined to see certain things, Which reminds me of a similar Russian saying, albeit not quite the same as the English one:
('Where the neck goes, the head follows.')
