MORIMOTOM pretty much summed it up.

Flicking a knife is an activity that has the potential to damage the whole lock mechanism. It causes the parts to slam together, creating unnecessary wear. Flicking the blade open once in a while it is not a problem – in fact, we recommend it as part of the assembly process. It is the compulsive, continuous snapping open of the blade that is a problem; the spending an afternoon in front of the television and flicking-your-knife-open-breaking-the-lock-closing-it-flicking-it-open-again for the duration of a football game, or movie or whatever, and doing it every week.
This is as true for Sebenzas as it is for any other knife – or any hinged mechanism with a stop and a lock. Of all the knives on the market, the Sebenza is best able to withstand flicking because the size of the stop pin/sleeve, and the configuration of the pivot bearing and bearing surface, cause the energy to disperse over a large area.
Here is an analogy that illustrates what we are trying to say:
A man owns a Porsche – it is a well-built car and the whole vehicle has a “bank vault” feel to it. He particularly likes the sound of the doors closing – thunk. To work off his obsessive frustrations about life at large, this man spends hours and hours just opening and closing the door. Eventually the hinges wobble and the doors whistle when he is driving because they don’t close securely any longer. Do you suppose Porsche will replace the doors happily and at no charge?
So in summary, we do not advocate flicking knives at all – it is not in the best interest of the knife – any knife.
