How safe/reliable is the 'locking' mechanism of a switchblade knife?

Question

Just got a switchblade knife or an automatic knife, and you open it buy pressing a button- you cant open it without pressing the button. And it closes by pressing that button and pushing the blade back into place- and you also cant close it without pushing that button.

Answer 1

It depends on the quality of the knife and what company made it. If it came from China, don't depend on it too much. :-)
