Okay, I am a newbie so don't shoot me if I overlooked something. For a holder for this knife, you were talking about using plexiglas (I am assuming to make it look more ethereal). Might I offer the suggestion on it? A plaque to hang on the wall and you mentioned you wanted to mount it vertically. Two pieces of plexiglas attached perpendicular to the plaque itself. Top one has a triangular hole cut in it. This will allow the blade to penetrate it but will not allow the handle to go through. Then consider a second piece at the bottom with a divot drilled in to it just enough to where the tip of the blade is suspended in it. For extra security fill the divot with silicone caulk and after apply a little oil to the tip of the blade, insert the blade in to the holder how you want it to display and let the caulk cure. This should give you the holder you are looking for but protect the tip from spearing something accidentally and with the added security of the caulk should keep it from rattling around much if you live near a busy street or are in an earthquake-prone area.
