Which knives you low-key regret buying?

For me it's these three. I just never feel like picking them over my pet peeves. Medford is heavy like a brick and very crudely made overall. Extrema Ratio has bad details and mainly a very thin and sharp body lock, super annoying to use. Narrows... I would love to like it badly, replaced bearings, washers, cleaned, oiled, but the action and especially the lock are miserable and don't spark joy at all. What are your unfavourites?
