I just enjoyed playing with my balisongs and like you, I loved the design of them. I'd 2 Pacific Cutlery knives and it broke my heart to get rid off them.
I trained in Inosanto/Lacoste in London and I also had a work colleague teach me a blade system that he learned back home. The latter is very basic but I really liked it's practicality and the attitude that came with it. I'm also a mad man for stance and footwork and that was the complete core of the training. I've also trained in muay Thai, Krabbi krabong, wing chun as well as some shooto, judo, BJJ and Wado ryu.
Sorry I called you by your surname in my last post. The error is due to my vanity disallowing me to wear my glasses :-)
We're not allowed carry blades of any kind here in Ireland. Equalisers are the best thing for us to have. Metal palmstick-type keyring, pens an old brick-type phone and old car keys for me.
I carry either the Gunting LLC by GM Bram Frank or the Abaniko by Bram Frank at all times. Besides the fact that I have found the knives to hold an edge really well and be nearly indestructible through several tours in Iraq and Afghanistan, they are designed with FMA practitioners in mind and are a legal carry (4" blade) in nearly every state . In fact, I highly recommend the entire CSSD modular knife system if you get a chance to check it out.
