I think it really depends. As much as I jones'd for a Sebbie after getting my hands on a couple. I wanted it even more. But pragmatically, I'm a city/suburb guy and I have no real way of working a sebbie small or otherwise into my EDC. I had been thinking about this for about 8 months now and I ended up being too pragmatic.
If you are going to carry and use the snot out of the Sebbie I'd say go for it. It's a really weird knife at the end of the day. The ergos kinda suck, it doesn't open as smooth as a Benchie (comparing this to a Pinnacle 750) or Spyderco, and it doesn't slice as well as a FFG Spyderco but if you like the beauty of simplistic knives, the S30 is nice but so is VG10 and 154cm and 440C in terms of good steel. The sum is greater than its parts though. To date, I haven't had a production knife in my hand thus far that felt as quality as the small or large Sebenza. That said I came to realize that why I wanted a Sebenza is not reflective of my EDC needs. I EDC a peanut by the way.
To be honest it's like what Fetzer said, this itch will literally not go away. If you pick up a Sage 2 or other Ti framelock, in the back of your head you will still have this need to try out a Sebenza.
If I hadn't held and played with a couple multiple times I would have pulled the trigger already as that itch needs to be scratched ain't now way around it! At the end of the day though, whether it's a ZT or BM or CRKT or CRK, if you keep the edge in good shape, you will be able to cut things with no issues and I've only seen a handful of knives on the forum thus far where the user basically used the snot out of the knife everyday and even with that it took a decade for that knife to be retired. Most production knives are capable of being used that way in my opinion.
