A 110 for sure.
The 371 and 373 stockmans, depending if you prefer a "large" or "medium" stockman, 389 canoe.
If you can find a 301 or 303 stockman at a pawnshop or yard sale, they would be a good choice.
The 37x and 38x are made offshore, but still have the same forever warranty as those made in Idaho.
The 877 is a pretty good fixed blade. It isn't the same classic style as the 100 series, but it does the job.
If you find a used one, be aware the 877 with black handle was made offshore for several years.
Walmart had the 877 with a white handle. Those were made in Idaho. The black handle has been made in Idaho since then, too.
I guess Walmart ordered enough of them that it paid to move the manufacture of the 877 to in-house.
A used 100 series is always a good choice.
Like you I am on a limited fixed income.
I suggest the 371/373 because they are roughly half the cost of the 301/303. From my experience, they do everything the Idaho made knives do. I really have not noticed a difference in edge holding between the domestic and offshore 300 series.
