Matus,
An EDC is just that, for tasks that come up day to day - a $300+ knife is not usually needed. ( We all want the best, all the time, I know.)
Keep and use the Leek! I have large hands and can comfortably fit four fingers on the handle. The thin blade should slice adequately and the 14C28N steel is closer to ATS-34 than AUS-8. Great fit and finish and you won't weep if you lose it.
If you want to step up a bit, think about the CRKT EROS. The blade is similar but has less drop and more belly - Acuto+ steel is similar to VG-10. The Ti frame is CNC machined and looks great, very thin and light. The fit and finish is great and the frame locks solid. CRKT is known for spotty CC but, in this case they are spot on.
Both of these knives are flippers, but the EROS uses the IKBS system.
