I was discussing international knife laws with a friend in Germany and he told me that he gets to carry a one handed opening knife which does not lock or a locking knife which opens with two hands. This got me thinking whether I even know a locking knife which was designed to be opened with two hands and that's what we're looking for here. So no thumbhole. A removable thumbstud or axis/compression lock (flicking it) would be a legal gray area. Do you have any recommendations? I know that Spyderco makes the UKPK and DK for regions with strict knife laws, but he is not looking for another slipjoint.
