Hello, i am french.
Not really knife collector and specialist.
I am interrested since few years only, then i will give my begginer and personnal point of view.
You are right, French knives are not very modern regarding opening systems.
Some knives makers makes great knives with flip opening for example, but mainly knives are "piémontais", friction, slipjoint or linerlock with two hands opening.
Is it cultural ? Maybe.
I feel like my grandfather with a knife in my pocket, then i open my knife like a grand-father.
If i want a very fast and very strong knife, i use a fixed. what else !
In France, knives are not authorised outside. In the street, in your car, even in hike/trekking/camping, it is not allowed to wear a knife.
Policemen can also juge by himself if you are just trekking or hunting and need a knife to prepare a small campfire or if you are a menace.
In all the case, the law said "unauthorized".
Then, for collectors or knives lovers wearing a knife may looks strange for a large part of the population.
They can call you "The xxx guy with the xxx knives".
xxx = Crazy or nice.
Then, having a knive outside your home (outdoor, friends, restaurants) for eating or for small work could be done with a discret knife.
A traditionnal friction, slipjoint or a light line lock is ok (or appears ok).
And of course cheap : in case it is confiscated (Opinel, swiss knife or old traditinnal are the best choice).
Having a fast and noisy automatic/1-hand knife and you replace the xxx by "dangereous" or "freak", no more "nice".
This was my personnal point of view.
Know, many french people appreciate spiderco, benchmade or modern asian knives (with hawful stainless bleeeaade).
In France, there are certainly few "rapid" opening knives makers for i.e :
