I love the look of that knife but could never have one because the scales overlap in the wrong direction and I just can't deal with that. When the knife is open, the scaled creature would move as if the blade was its tail and the back of the handle was the head.
It's like really bad physics in a sci fi or action movie, which makes it unwatchable.
I and quite a few other people pointed this out to WE and they just said something to the effect of, "One person's vision is different from the next." And me and the other people were like, "Yeah but the scales are backwards for real though. It straight up looks dumb."
