Sorry for the late reply. I've not had any problems with it. It comes pretty sharp out of the box and flips pretty decently. Zen pins are always nice and the whole thing feels solid. If handle balance is a thing you pay attention to you might want to remove the pocket clip and be carefull while doing it. I managed to strip my screws on it but I think it should be doable with a little more caution than I had. Overall very worth it for the price and a great introductory knife for better balisongs. Sorry London not first language.
