That is such a sweet pipe tool, what a find!
Actually there are quite a lot of forges which may brand their products with the Laguiole label. One of the top ones is "Fontenille Pataud", and they usually command a price around 150 to 300 Euros, with lesser ones being "en Aubrac" or "La Fidele".
Then again, I'd always opt for one of the cheaper ones as well, because blade steel quality shouldn't be such an issue with a pipe tool.
Again, very well done!
