Familiarity: I've put it through the wringer
I mean what else can you ask for in a knife? I used this all of last summer as a mountain guide for Team Ascend Trek in Colorado, and it was easy to operate in terms of folding and unfolding, it stayed sharp enough to cut rope and parachord with ease, as well as cleaning these trout I caught on a rest day in Brown's Creek up above 12,000 ft between Mt Antero and the Tabeguache Peak/Mt Shavano ridgeline. Sadly I lost it on a ski trip over spring break...so I'm buying another one for this summer. That's how much I liked it.
