I could not find a knife display stand on this site that suited my needs, so this is what I came up with.

As reference:

The folder with carbon fiber scales is ~180mm long (printed at 0.75x length) .

The hunter with camel-thorn (Acacia erioloba) scales is about ~235mm long (printed at full size).

The Santoku with Kiaat (Pterocarpus angolensis ) scales is about ~295mm long (printed at full size)..
