Wally, very good point and the topic of conversation between mitchell and me. The knife is "comfortable" in the upside down carry mode as intended for fighting, but not so much for utilitarian use. That is why we think that Bo did not make many (maybe 10 or less?) in that configuration, but probably more in the vein of the one pictured in Gaddis. It has a conventional stag handle.

Mitchell's knife was made June 1942, and you have to remember Bo switched to leather almost exclusively in November 1942. We know he had made only 28 knives by 7 January 1943, so his total production during that period was very small.
