I know what you mean, Pasha. It's something I have wondered myself.
I've been lucky enough to have traveled via being stationed overseas while in the army, and being a knife affictionado, I took notice of what knives were being used around me. My MOS was of the combat engineers, and we were on construction sites at many army and air force bases, and worked with local personal that did a lot of the grunt work.
While in West Germany, I never saw a German worker with anything but a low cost sodbuster type of knife. F. Herter seemed to be popular, as was the single blade slip joints by Linder. Plain and simple was the order of the order of the day. If a more upscale knife was used, a stag handle Hubertus or Puma was seen once in a great while. But all were simple single blade knives. The only multi blades I saw were sak's.
In Italy and France it was the same thing. Single blade knives of modest cost. Lot's and lots of Opinels, some Laguioles here and there, one Nontron, and a Douk-Douk or two. And sak's.
In England, doing some work at the Lakenheath air base in Suffolk, we worked with local cement contractors and suppliers of construction materials, and I don't ever recall seeing anything but medium size clunky single blade sheepsfoot blade knives. Plain iron bolsters or all stainless steel type of knives kind of rough finished. I know the British cutlery industry made tons of very pretty multiblade knives and dressy pearl handle knives of all types, but I never saw them. Maybe they were not sold to the blue collar guys who stood shin deep in mud laying a pipeline out to the local water and sewer systems.


I never made it to any gentlemens clubs in London when I was there. Pubs, yes. Drawing rooms, no.
I know that the European cutlery firms made them, but either they were made for export to the U.S., or they were sold to
people who didn't spend their workday on construction sites. In my own experience, almost all the pocket knives I saw in Europe were mostly low cost single blade folders. I can only conclude that some kind of cultural thing was at work. The last time I was in England and Germany as a tourist, I saw lots of sak's.
