It's a new addition, so it's hard to say. My previous SAK was a Champ, and I used the metal file and scissors the most, but I always wanted a bit driver for the electronic maintenance that I do.

I carry the cybertool L on a daily basis for 2 years now. I love this thing and couldn’t imagine leaving the house without it. Even at home I often carry it in my pocket as it comes in handy that often around the house. I use the knife, pliers, scissors and bit driver the most, but I even had many usecases for the file and saw in the last years. Once I was spontaneously helping my mother changing here offices floor (click vinyl). The saw and file were live savers as my mother didn’t have the right tools around and made it possible to work faster and more precise than I could have ever imagined. The bit driver is perfect for every task I used it for (only downside is that it’s not placed in the middle, that makes it a bit unhandy sometimes. But it gets the job done). To sum up, this SAK feels like having a whole toolbox with you all the time, making it feel like being prepared for everything everytime!
