Which one should I get next?

Try the Kapara or something in K390, especially serrated K390 if you can find it.

I have been interested in the cutting power of K390 serrated.

Another one not mentioned yet is the Resilience, it's the large liner lock in the same family as tenacious.

From a collecting perspective, I do like the idea of adding a knife from Taiwan . . . maybe the Cat.

- Tenacious (M4): This is my "utility knife." I find its "liner lock" easier for one handed closing than my "back locks" and "compression locks." Cuts up boxes like a laser beam.
...

Always like when people realize how most natural and easy a linerlock really is to operate, imo a underappreciated lock type in Spydercos lineup! Would not complain about more mid to high quality linerlock models!

(Some suggestions concerning backlock operation you can see here viewtopic.php?p=1366139#p1366139)

/ Yes, the Tenacious is a great work knife, especially the long edge in that very compact knife makes for really efficient cutting!
If you like the model, some day in the future you could also consider the S35VN lightweight version (actually not THAT much lighter than the G10 one, but with grippier scales and a bit more handle chamfering).
In that case I´d take the comboedge variant (unfortunately there is no full SE Tenacious LW in S35VN)

Reporting back . . . I bought a Dragonfly 2 with Black FRN and VG-10. Decided my capability gap was not having a blade under 2.5 inches for carry in a more (blade length) restrictive nearby locality. (It does look great next to the Endura and Delica.)

I sure hope you went for SE...

Not a bad choice .I carry a Dragonfly Salt in weak side pocket nearly everyday . Incredibly handy knife . MG2
