It’s theoretically possible, I suppose, but there are two things to think about there. First is that commercial knife makers, particularly Benchmade, use a similar sort of mechanism on several of their knives and I haven’t spotted any lawsuits about it in the news. And second, the way a balisong knife works requires at least one of the handles rotating a pretty good ways before the cutting edge is really presented. I think that’s unlikely to happen in your pocket. In fact, some of my balisongs with more annoying latches I carry in the unlatched position to begin with and I’ve never had an issue.
