The only experiance I have in an environment where there was actual working cowboys, was living in Trinidad Colorado in 1977 and 78. There was three well paying jobs in Trinidad in those days. The Allen Mine comapny who owned the coal mine at the base of the mountians, The Denver-Rio Grande rail road who operated a large rail hub just outsie of town, and all the ranches on the flat land east of town. The flat land was cattle ranches, and we had bars in town that catered to them like the Siver Spur, The Silver Saddle.
I recall seeing a good amout of Buck 110's in the ubiquitous black belt pouch, but there was one knife that was VERY popular. I'm not sure of the model number, but it was a Schrade Old Timer, and it was a large lockblade with brown sawn delrin handles. The lock was a brass liner kind of lock like you see on the screw driver blade of the TL-29's. The number 125OT comes to mind, but I would'nt want to put money on it.
For some reason, these knives were the most popular among the real working cowboys from Model, Hoene, and the ranches east of town. Maybe it was a Colorado thing, like the basque herdsmen carry a particular knife for their region.

I do remember one cowboy telling me he liked a knife he could get to and open while wearing leather work gloves.
The miners on the other hand seemed to really like a utility type of knife. This was the age before Ron Leatherman came up with his thing, so there was alot of surplus military scout kind of knives carried. What some call a demo knife.
It's funny how a geograghic region and occupation can have a tool/knife all its own. Local culture has alot to do with it. I remember when I was in western England and southern Wales, one shepard was amazed at my stockman. He asked me with that wonderful accent " 'ere now, wot'cha be needing all those blades for, eh?" He and all his mates to a man carried a single blade jack with a large sheepsfoot blade. For them it was the be all, end all knife.
In the end its each to their own I guess.
