I wasn't around on BladeForums in 2009, so... yep, I have a G. David Arbalete, the Extra model with a corkscrew and punch. Horn handle, carbon steel blade. I have carried and used it daily since December 1989, thus 29 years, 7 days a week. And I still love it. I probably made small corrections to about half the wall planks in my home with this thing, and practically every screw in wooden objects has been pre-drilled with it. The punch also makes a great scraper - it is huge, presumable to be used by farmers to punch a hole in a cow's belly to let gas escape when the animal has a colic and could die...
The slipjoint is still tight after all these years, no play at all. True, there is no blade stop so you have to get into the habit of closing your knife calmly. Do not consider such a knife as an alternative to a one-hand opening, automatically locking 'spyderco' style flick knife. This is not a plaything where you use the opening/closing action as a fidget spinner. It is a valuable tool to be respected, for repairing fences, opening bottles, building a house, opening bottles, scraping mud from your boots, opening a bottle, cutting bread, spreading paté, opening a bottle... (do I need to mention that Laguiole corkscrews are considered to be among the best in the world, and that the dedicated sommelier Laguiole knife, no matter the brand, is the ultimate tool for serious wine lovers?).
G. David (today called Genes David) claims to be the oldest manufacturer of Laguiole-type knives. The company as it exists today goes back to 1922, and it seems that about a century before that, their founding family already made knives. A less known fact is that David, situated in the city of Thiers, has for a prewtty long period been the essential supplier of knife blanks to knife makers in the town of Laguiole - often small workshops where they added their own handle scales and such. The modern 'Forge de Laguiole' is not a company with a long history where 'Laguioles are still being made'. In fact, for a while there has been a period when no knives at all were being produced in the town of Laguiole, until someone decided to set up the modern Forge de Laguiole to restart knife making activities there. So Forge de Laguiole is in fact pretty young, certainly compared to G. David and a few others who just continued to produce Laguiole-type knives in Thiers, the French knife-making capital. Which means that if you are looking for a Laguiole made by a company with a truly long and uninterrupted history of making these knives, you go to Thiers. Just sayin'.
There may be others (FP) that make Laguioles even more refined, yes with a blade stop and with all sorts of luxury finishings, thus way more expensive, but if you want the best workhorse Laguiole knife that will earn you respect from farmers in any rural village café, go for a G.David Arbalete. If you can convince them to get you one in carbon steel, even better - a real heirloom Laguiole knife must have a patina.
Soem details that some people may not notice: the bolsters are brass, and so are the metal scales of the internal knife structure. You don't make a carbon steel knife with a carbon steel inner structure that will get horribly rusty. The slipjoint spring along the back, however, is steel. The small brass pins in the side of the handle scales are supposedly used to symbolize a Christian cross - stick the knife upright in a chunk of wood and you can pray. Or maybe ward off vampires. A century ago this may have been important to traveling farmhands.
Finally, Laguioles are legal to carry in France, after some court cases where judges decided that 'Laguiole knives are not to be considered weapons but traditional culinary tools'.
Get one, you won't be disappointed. As long as you don't try to baton a 6-inch hardwood log with it of course. ;-)
