Balisongs is my main point of interest. Both of those balisongs are CCC balisongs. They are cheap for sure so they make great beater knives, while they can flip they wont be the best flippers as they wont be overly balanced in terms of dynamics. Also here is my philosophy on balisongs.
Just buy the more expensive ones. The reason I say this is because, if you buy the cheap CCC and you end up loving flipping, then you wasted your $20 because you will need to buy a better knife. Or lets say you buy a CCC and you end up not liking flipping, then you just wasted your $20. Although if you buy the nice BM balisong, and you end up liking flipping then you wont need to buy another balisong immediately. Conversely if you buy the expensive BM balisong and dont like flipping you have two options. Keep it, it still is a great knife after all, or, just sell it, which will be easy. You cant go wrong with a BM balisong. Although a kimura is a great first balisong as well.
Sorry if that was confusing it might take a few reads. Although those are alright balisongs in a general sense. Balisongs are just amazing, and once you buy one you will for sure buy many more.
Also they should hold up for a little while, although that depends, on were they get dropped, if they get dropped, and what tricks are being done with those balisogns.
