Thanks you all for the comments. I think finding at least one sheath for the old 5's will be one of the most difficult/longest searches in my RMK collecting "career".

Peter, I had got the knife on Thursday morning and left it at the hotel the rest of the Show. I did not want you to be stressed over an Ironwood knife that was not yours. Besides it could be embarrassing to see two grown men wrestling over a knife at the Blade Show! Truthfully I forgot about bringing it back to the Show.
