Serrated blades are a breeze to sharpen with a Sharpmaker (as is most any knife).
I have many sharpening systems/ tools but find it's hard to beat the quick and easy Sharpmaker. A lot of bang for the buck!
The Yojumbo I received directly from Golden has the most secure detente of any compression lock Spydie I've handled (over 50 for sure).
Knife is big when open but really not very large in pocket. G10 is super grippy! Given your likes Vivi, I think you would appreciate it for EDC use.
