I find myself wanted a blue / black G10 Vantage Force Pro. I've seen a few reports of knives with very late lock-up, and / or off-center blades. These are two issues that really bug me in a knife. I was hoping to hear from some Force Pro owners on whether or not your knives have any issues. I'm guessing that the vast majority of them don't, but I'd like to get some more feedback before I pull the trigger on one. I'd also like to hear how they are holding up over time. Thanks in advance
