Going out on controversial ground here, but I never did fancy lockbacks. Linerlocks or framelocks were my style, until Benchmade came up with the Axis lock, my favorite nowadays. Nevertheless, I like lots of aspects about Spydercos, and generally user feedback and costumer loyalty speaks highly of these lockback models (Delicas and Enduras sping to mind). My doubt is, am I best served with Griptillians, or would Delicas be better off (regarding lock methods)? Can anyone compare the two "families"? Are they in the same performance league?
