We make ALOT of knives without "our" brand name on them, but they usually have another knife companies marked plainly on the blade[ we do alot of contract manufacturing]. I cannot think of any knives that we made recently [in the last year or so] that we didn't mark. If you have any idea what these knives are [model, etc], lemme know, and I'll try to find out.
Thanks for the interest!
