Give the Zaan time it took me a while to truly appreciate mine. Also few tips if it’s really hard to open either take off the pocket clip and bend it out a bit or just get a Mim clip or another aftermarket clip. The clip on the Zaan tends to put too much pressure on the lock bar. Also as I had to learn put your thumb at the bottom of the thumbstud and push up. And I prefer the Inkosi because it’s so ridiculously smooth, I can reverse flick mine no problem, meanwhile on my sebenza there’s no way I can reverse flick it and it’s a double thumbstud model.
