they are just a off brand , no commotion , they shave OK ,nothing special !! i would probably not buy anymore if i was you !!!
i have a Greaves wedge that is also wedge less , i wondered the same as far as if it lost its wedge or someone forgot to put one in during assembly of the razor .. my blade sets high do to a slight warp in the horn and the only thing keeping me from taking it apart and adding a wedge is that the scales have no damage as far as bug bites , chips , or cracks , and the original collars that im pretty sure i would almost damage trying to drill the pin out , so my edge dont hit the scales and the scales protect the edge , so im just leaving mine be ..lol
