The Buck 371 and 373 Stockman are indeed made offshore.
HOWEVER
The Buck
301 and
303 Stockman are made in Post Falls, Idaho, USA.
Now, do you like a "light" pull of say "3" to "4" or a slightly heavier pull? (for comparison, a 92/93 mm SAK has a "5" pull on the blades)
If you like a lighter pull, get the Buck 301, if you like a "Large" stockman, or the 303, if you like the "medium".
If you want a slightly stiffer pull, the offshore 371 and 373 are around a "5", as are the Case, from all I've heard.
Be aware the Buck knives are a
Three backspring design, whereas the Case (and most other brands) are a
Two backspring design, which requires kinking the blades to fit them all in.
I've compared the over-all thickness of my Buck 301 and 371's to Rough Rider and (offshore made) Schrade stockmans. The Rough Rider and Schrade are both two spring designs. The Buck with three backsprings is just as skinny across the covers.
Case does offer a Stockman with "True Sharp" stainless steel blades, as well as the CV carbon steel blades. I don't know if the Navy Blue Jigged Bone is available with Ture Sharp blades though.
Case offers more cover/handle choices than the Buck 301 and 303's basic black.
The 371 and 373 are offered with different covers/handles than the 301 and 303. I don't know if they are currently offered with wood or amber jigged bone, or something else.
One of my 371's is a barehead (bolsters only at one end) with black and blue G10 covers.
Keep in mind that although made offshore, the Buck 371 and 373 have the same Forever warranty as the knives made in Idaho, and you are still supporting a US manufacturer if you buy one. (and saving a few dollars, to boot.)
Personally, I prefer the 3 spring design of the Buck. I just wish they made a true "large" (4.25 inches or greater closed) Stockman.
Buck or Case, whichever you get will be a fine working/EDC knife.
NOTE: The "light" pulls on the Buck 301 and 303 are not a "Defect".
The job of the backspring is NOT to keep the blade open. The normal cutting action (unless you are doing something stupid) forces the blade open.
The backsprings only job is to keep the blade from opening when the knife is in your pocket, and from flopping half closed when it is open. The 301 and 303's backsprings are plenty strong enough to do their job.
I've never understood those who want a "7" or higher pull.
Why fight your knife to open it? Especially if/when your hands are cold and/or wet.
