Displaying a knife collection is not all that easy and sorta depends on how much room you have, and whether you want to go horizontal or vertical, buy or build. I have a rather large collection and had them in a display case with shelves and glass doors for years. I moved about a year ago and repurposed the case, so had to put the collection on shelves. For one thing, keep the blades well oiled. Secondly, take a look at Pinterest which will give you so many pictures of display options you want know what to pick.
