It is "more better" but the Delica is about the smallest knife that it works on. Karahawk doesn't seem to like the wave... Here are my Spydies. Waved Delica is center left top photo and Karahawk is second from left top (with the thumb hole). Wave is best on the Endura/Matriarch. There are three Enduras in the photo (center right top photo) including my first Spyderco (the green handled Endura in the center). My wife claimed my pink Endura for her own so it is not pictured. Sadly, the second photo needs to flip left to right and rotate 180 degrees but the size of each knife makes this obvious. Top photo, bottom right Military and center right Waved Endura are EDC.

and yes, I am partial to the Spyderedge serrations... and three have neck sheaths (ARK, Yojimbo, and Military.). Ronin has a belt sheath as it is my only fixed blade Spyderco. I had a Byrd (Flat Byrd? like the Spydercard but cheaper), but gave it away to a kid at work. No comparison to original Spyderco. Just need a Gunting and a Warrior...
The ARK was dismissed earlier in the thread as a novelty but it seems that there was a lot of thought behind it...
Technical Specs
The ARK—or “Always Ready Knife™—is a purpose-designed personal-defense knife conceived by U.S. Army combat veteran John Shirley and his friend Sam Owens. While deployed to Afghanistan, Shirley learned that an alarming number of U.S. personnel were falling victim to sexual assault, particularly while showering. Drawing from his knowledge of the Japanese martial arts and with the help of Owens’ skills as a craftsman, they developed the ARK as a lightweight self-defense tool that can literally be carried anywhere.
The heart of the ARK is its deeply curved clip-point blade ground from H-1® steel—a nitrogen-based alloy that is extremely corrosion resistant. The curved edge packs impressive cutting power into the compact blade and the clip-point profile ensures a strong, extremely sharp point. The ARK’s fiberglass-reinforced-nylon (FRN) handle is molded directly onto the tang and features Spyderco’s proven Bi-Directional Texturing™ pattern and an index-finger groove to guarantee a secure grip—even with wet hands.
To ensure universal carry, the ARK includes an injection-molded polymer neck sheath with a breakaway ball chain. Best of all, the ARK and its sheath together weigh only 2.0 ounces (57 grams), so you’ll hardly know it’s there—until you need it.
