If it's a proper name, you need toask the person/company who created it.I think it's a business name of a small bookstore and digital content services that I saw while walking around the city.
It seems to have a purely local significance, and if you got the impression that it's the name of a business, than it probably is. If it's a name I'd expect to see capitals though: Able Knot.Can someone please help me? What means 'able knot'?
