1. Bearings are great for people that like to "play" with their knives, but I don't think adding more small moving parts to a folding knife is a good idea. They turn a serious, useful design into a "toy" in my eyes.
2. Same with flipper tabs. There are too many factors involved that have to be just right for them to work reliably.
3. Steel liners on a FRN handled knife like the Delica or Chaparral are unnecessary. They add complexity and parts to knives that should be light use and simple.
4. The compression lock works perfectly fine for southpaws, and I think it works better for left handed people than right handed.
5. "Ergonomic" "curved" handles are actually detrimental to use and handling. More neutral handles with nicely rounded edges are better.
6. Standoffs are inferior to backspacers. Again, they add unnecessary complexity, and add more hot spots compared to backspacers. It's not that much harder to clean a knife with a closed back.
7. Drop shut action seems more like a design defect to me.
8. Flippers aren't the problem. People that buy from them are. The only way to deal with them is to not make it worth their while to buy up all the knives.
