FWIW, I don't think that the Raven 2 "exceeds the Tenacious in just about every way."
Apart from the ergonomics, the main difference is the blade steel -- CTS BD1 vs 8Cr13MoV in the Raven 2 and Tenacious -- which is the main advantage that the Raven 2 has over the Tenacious. Otherwise, the blade & handle length are essentially the same, they both use a liner lock and handle material is also G10 for both. So, there really isn't any other significant difference between the 2, except for the use of the teardrop vs Spydie hole in the blade.
So, if the knife is going to be a heavy "user" and you can get both knives for the same price (which you can), then the Raven 2 would be the better buy. However, if you don't plan to use the knife for more than cutting open a few letters or boxes, it really doesn't matter which you choose.
On the other hand, there is the generally negative "stigma" associated w/the Byrd line, as just cheaply made Chinese products to fill the lower priced knife market (which it is). In Spyderco's words, the Raven 2 was produced in order to "usher in a new era for the byrd line" but why buy a knife with such negative brand connotations, if you can buy a knife that doesn't suffer from such stigma, even if the knife "rocks" in other ways?
If you don't care what other people think, then it doesn't matter. If you own a lot of other knives and this is just one of them, it also doesn't matter. But, for someone who cares what others think, only has enough $ to buy a few "good" knives and doesn't plan to use the knife for cut more than paper and cardboard, the Tenacious would probably be the better choice.
I'm not saying that the Raven 2 isn't worth buying, it is, but there are other things to consider when buying anything (knife or otherwise) and for the OP to stick with his choice to buy a Tenacious instead. Or better yet, bite the bullet and buy a Para Military 2 or Para 3 instead which also arguably far exceed the Raven 2 "in just about every way."
