I used to have one in high school but I'm pretty sure I bit myself with it and gave up on it. Over the years I got more into good folders and recently autos, since they are more tactical/useful, etc. But a work buddy loaned me a trainer balisong to mess around with and I forgot how fun they are, especially when there's no risk of cutting my off. so I'm wondering if there's literally any reason to get one, get a trainer, and get back into it. I remember that scene in the punisher movie is bad , and it's pretty old school gangster, but I'm wondering if modern folders and autos have done away with any need to have one and practice with it. any reason to own one, practice, and EDC it or not so much?
