Been flipping balis for almost 40 years. Find some one that owns both of the older BM or PC sizes. I have large hands thereore I prefer the handles on the Custom Balisong. But since BM won't make them any more... but I digress. It took me a while to master the short knives 68, 35 etc. They flip fine when you get used to them. I find the 42 and all other ti handled balis just too light to suit my taste. Having said that, the 42 flips just fine. Might be easier to learn with the large knife. If you are just starting out, TAPE the edge or wait until you can get a BM trainer.
