How is 425HC "not very good anymore"?
It's not a "Super Steel", but that does not make it worthless or unuseable.
It's resistant to corrosion, easy to sharpen
without needing an expensive SiC or diamond stone, or some powered sharpening system, it's tough, and holds an edge well. In short, it does the job very well for the majority of Buck's customers.
If you want a "Super Steel", check out the Custom Shop (S30V is an option on some) and the SFO's by SK Blades and Copper & Clad.
SK. Blades' Smoke Jumper 110LT, for example, has a CPM-154 blade. As will their soon to be released blue handle 110LT with a drop point blade.
While not my style of knife, SK Blades also has some of the OHO Buck knives with upgraded steel, as well.
While not a "Super Steel", C&C has most, if not all, of the 100 series fixed blades and folders available with a 5160 carbon steel blade, and different handle options.
As for their Imported knives being "unimpressive" ... I can only speak of the 371, 373, 374, and 389 knives, since those are the ones I have.
They are "impressive" in what matters:
They get the job done.
They might not be the most impressive in looks, but they are impressive in functionality.
(They also have the same Forever Warranty as the USA made knives.)
FWIW "Affordability" is based on income.
I'll agree the Marksman looks like a great knife.
However, with an effective fixed income of roughly $650 a month (before paying bills) it is not "affordable" for a thing like me ... not much is, to be honest ...

(I am a "thing". I
almost look "human", but I've never claimed to actually
be one.
