Quali-kraft was a Japanese made tool brand made for the North American department store trade, the wrench looks and feels like a quality item. I'm not sure about the odd-shaped jaw cutouts, it looks like they are trying to contact the flats of the nut instead of the corners, and also a feature to "ratchet" the wrench on the nut. And it's "patent pending".
The weird jaw on the open end could be an attempt at a ratcheting open end wrench. Other manufacturers have tried it with limited success.
