I'm taking a second look at the "oddity" Cap is speaking about. First I thought it might be the camera angle but if Perry authenticated that knife as a 20 and I'm not disputing the fact, that blade does not have the "belly" and profile of a 20 as we know it. The whipped cream is that awesome caramel stag and fingertips. Now that would be a rare knife in every sense of the word.
That sheath almost looks like it would work with a 8-4X.
