Gif of one handed Mnandi opening in case you were curious. It's a newer one (Oct, 2016) and you just pinch the blade on either side where the cutouts are. You certainly can't flick it open, but if you want to you can still get it open pretty fast (under half a second once its in hand, counting picking it up I was still able to do it in under a second). If you've got the money its not uncommon to find them on the forums here for around $350, and getting them used you know what the wood will look like.
That said, it's hard to argue against the pakkawood dragonfly or Mcusta if you're looking for something closer to the $100 range.
