I use one as my daily! I practice with it a lot and have a trainer to practice. Funny enough, I actually just modeled mine today in a photoshoot (am a circus performer)
As a daily they function as any other knife. If you’re experienced with them, you don’t even think about open or closing. There’s a tiny bit of security in knowing that most people are too afraid to hold one. I do also like that they absolutely can’t close on you while holding it.
I have cut myself though. The worst was when I did a toss that landed tip-down on my palm. But small harm doesn’t bother me.
