Not a perfect apples to apples comparison
I'm sorry, but that's not even an apples to oranges comparison*. Here's a closer comparison. That CJRB Feldspar with the 3.5" blade is $40 from Blade HQ (not fake knife riddled Amazon). Then Tit's $50 to get the 3.5" Feldspar with a black coated blade, or $80 to get the BHQ exclusive with a black coated CPM-S35VN blade. You could the USA made Buck 112 Slim Pro (3" blade) at $80 or 110 Slim Pro (3.75" blade) at $90, both with G10 handles and uncoated S30V blades. Not perfect since we're comparing different lock types, and coated vs. uncoated blades and hardware, but a much closer comparison with truly equivalent materials. The price gap shrinks when we get playing field closer to level.
And that might be within many budgets
I agree. So, let's look at an alternative Chinese made knife at slightly higher price. The base CJRB Feldspar 3" D2 blade is $35 from BHQ. The CRKT Pilar III, also made in China with a 3" D2 blade, is $52. Both have black G10 handles, though one is a frame lock while the other is a liner lock. Still, they're pretty similar in size and materials. CJRB is a fully Chinese owned company. CRKT is a US owned and operated company, and they pay designers (like the Pilar III's designer Jesper Voxnaes) for their work. I think the extra $17 is well worth it to support innovative custom knife makers, and keep at least some of the profits here in the US; beyond the dealer markup, of course.
*The Benchmade and Spyderco knives that are linked as examples aren't even close to that CJRB. First, the BM and Spyderco examples you chose have black coated blades made from much more expensive steels and much stronger locks vs. a CJRB with with a liner lock and an uncoated blade made from a much cheaper steel. Next, the 560BK-1 actually has a CPM-M4 blade, not a CPM-S30V blade. Then, the Spyderco you listed is $168.70 MAP with a black S45VNV blade, or $154.70 MAP with and uncoated S30V blade. You do know that the current production black PM2s actually have S45VN blades, right? And that S45VN is a bit more expensive than S30V or S35VN, since S45VN isn't yet made in the quantities of its younger siblings. You could get a Paramilitary 2 with a CPM-S110V blade from a
reputable dealer for the MAP price of $196.00. Or you could get a Benchmade Bugout with S90V blade and carbon fiber handles for right at $200, since you're using that as your theoretical price point.
