I have now handled one funny folder.
The action is slightly awkward but gets better with practice, the knife is small so it's difficult to use the weight of the handles to swing around by gravity. It needs a little help. Also it was not perfectly smooth in it's action a little scratchy here and there. Considering the price of the knife, that's not unexpected.
The great thins was it was very slim, and the blade had a very nice edge on it.
