If you like the shape of the Endura but are price conscious, go for a Byrd Cara Cara 2: $15 for FRN, $25 for G10.
It will perform almost as good, and I think the difference is negligible. Collecting has very thick lines of demarcation as to pricing & rightfully so, but it would be tough to impossible to say that an Endura performs 3 to 4 times better than a Cara Cara 2 on the price vs. utility ratio. Mine was paper shaving sharp out of the box, has processed meat and fish flawlessly, and has served as a great secondary SD carry with the zip-tie mod.
There's a bunch of comparison vids out there, as well as deep reviews too.
The Cara Cara is a great knife and very well executed. I don't think any knife (within reason) performs 3 or 4 times better than another. If it separates matter it "performs", the rest is style points and preferences.
That said, VG10 has better properties than 8Cr13Mov even if negligibly so. The FRN between the Byrd and Spyderco can't be compared. Bi-Directional texturing IMHO is one of the best, if not the best, in the industry.
The rest as mentioned is personal. I think the Byrd hole doesn't work as well as the Spyderco but do appreciate the choil offered by the Cara Cara 2 over the Endura. The FFG is a very nice feature for the money.
If money is tight and you are looking for a great knife to use as a tool it's hard to fault any Chinese made Spyderco. However, if you are building a small collection some of them can become redundant compared to their more sophisticated siblings. A Crossbillcouldn't be compared to a Superhawk, but dang, for $25 it's a serious tool.
