Ahh, you are finding there are TWO different kinds of Buck Fever! (Sounds like you might be catching the more expensive strain.....)
The list of significant Buck models:
360 BuckTool
360WM Workman (substitutes a lanyard ring for one of the screwdriver blades)
360BK (black oxide finish)
360CM (Advantage camo finish)
360CL (with belt clip)
360FL (with file blade, two variations)
355 BuckLite
350 MiniBuck
350BK (MiniBuck, with black oxide finish)
In addition, there were also subtle variations during the production run, as well as models made and stamped with other logos, such as Harley Davidson.
