In spanking fiction when a implement is mentioned in the synopsis, that is synonymous to a Country or continent be that the martinet from France, the cane, England, tawse Scotland, the paddle North America etc, i for one do use that to help choose a story to read.
Each implement has a distinct history, cultural identity and individual diifferences from appearance, resulting effect upon the body part used against and manner it used by person applying it.
Merely the mention of for example the martinet, creates mental images and builds scenarios in my head that to a degree feed off stereotypical scenes of french basis.
I am not sure how that would work for my choosing of a story, if implement was used outside of its expected setting. Having an American wielding the martinet, to a 'naughty' Aussie lady whilst on a cycling holiday in the UK, it breaks all traditions, norms and expectations. 'Gadzooks' it would be just wrong on so many levels

........um but very interesting all the same, confirming not judging book by its cover i guess.
