Spyderco makes some great knives and has been driving innovation in the industry for a long time. That's not in question. Commenting just on the Tenacious being overpriced, is that really a question? It's a $50 knife in 8Cr13Mov and it's 2020. The non-steel material differences on the RAT might have mattered once upon a time but these days, features like G10 scales and actions that run on ball bearings can be found on ultra-cheap Chinese knives in junk steels like 3Cr13.
Here are some more clear-cut comparisons:
The
Tangram Santa Fe from Kizer costs less than $30. Fit and finish is good. Their Acuto 440 holds a better edge and is more corrosion resistant than 8Cr13Mov without being difficult to sharpen.
The
Petrified Fish 818 costs less than $30. It has G10, bearings, and an incredible action. Their Chinese D2 holds a much better edge than 8Cr13Mov. My only complaint with this one is that the inner scale edges (nested liners) benefited from a little filing. Of course, the same can be said about the Byrd Meadowlark, which costs about the same and uses 8Cr13Mov.
CJRB has a lot of knives that cost less than the Tenacious. Some, like the sub-$40 Feldspars, have received widespread acclaim. In my own experience, fit and finish is okay, action is decent, and their Chinese D2 holds a nice edge.
All of the sub-$50
Civivi knives...
I haven't tried any of these but
Ruike has a good reputation. Here are all of their knives that cost less than a Tenacious on BladeHQ. They use either 12C27 or 14C28N:

The point is that in 2020, the Tenacious in 8Cr13Mov is ludicrously overpriced at $50. Heck, the Byrd Meadowlark in 8Cr13Mov is ridiculous at its current price. Competition has really ramped up in the sub-$50 category. Companies like Spyderco, Kershaw, and CRKT have fallen way behind the times with overpriced knives in 8Cr13Mov. I'd love to see that change.
