You'd have to be a little more specific in your question, as to whether you were asking which weapons aren't issued by the military, which ones don't have origins in the military, etc.
With regards to the second one, the weapons originally used by ninjas were actually farm implements, rather than purpose-designed weapons. So those might be considered nonmilitary weapons. In the corrections system, inmates often fashion weapons out of newspaper, razor blades, mattress springs, etc., and those weapons certainly wouldn't be military weapons.
The question's a little too open to interpretation.
