I'm using ceramic magnets to hold the knife to the metal back board.
The sign on the left came with the display case, which I purchased on an online auction site.
I have tried finding information the this display case, but I have not had any luck.
I try not to buy multiples unless I'm planning on reselling it later. The only reason I bought two Zt500 b/c the one with the lanyard is a blem, and I couldn't stand to have a blem and not an original. The blem is the abuser, and the orignal is a a safe queen.
Same with the Zt302 and the 303. 303 is the user and the 302 is the safe queen.
