Laguiole and other patterns were used as work knives until the end of the 70s, then declined softly but surely and would have faded away.
In the mid-80s, thanks to several factors, including the Laguiole municipality' s aim to prevent the slow death of the village, the Laguiole fabrication in Laguiole was revived, aiming top end, rivalry between Laguiole and Thiers led in the 90s to more sophistication, it became trendy and kinda men's jewelry, tons sold as the
gift-when-you-have-no-other-idea and still do. The shop in the St Louis island, in one of the most touristic place is representative of that tendency.
Some years ago, I went at Kindal's to buy a pair of Parapluie poissons, there was a deep pocket family who came to gift a top end Lag to the elder son for his 16?th birthday. This would not have happened in the 60s.
Today's peasants have microwave ovens in their tractors and don't need real knives anymore for lunch.
Nevertheless, there are still lower end, utilitarian and less expensive made by le Sabot, G david, Chevalerias, etc. Counting the number of cutlers/assemblers of Lags would be a never ending job.
Unfortunately, many other patterns did not have that luck.
Charlie, don't know if this helps, here my Parapluie stamps :
