Spyderco Delica can be swapped around for tip up or tip down and left or right sided carry. It is easy to change around to find what works best for you. Put a little thread locker on the screws once you find the ideal orientation. I settled on tip up.
I experimented with the wire tie version of the Wave feature, it works OK and it pushed me to aquire an Endura with the real Wave blade. Kind of cool but not really needed.
I went back to the Delica as my everyday carry. Delica blade length is also friendlier at 2.875 inches.
