I think it's the 'THREADING TOOLS' label and pegboard aspects, Todd. Blue Grass tools are scarce enough. I'm not sure I've ever seen Blue Grass threading tools. But I know what I would do if I was a Blue Grass guy and I didn't have any tap and die stuff. I would remove the pegboard or cut a thin board, paint it red, and stick it inside the cabinet right over the top of the tap and die pegboard. Plenty of room under the glass. Plus, you have the drawer underneath. It's like your old Bonney 3/4-inch drive wooden display cabinet. Who cares if it's filled up with 1/2-inch sockets? It's the Bonney label on it that makes the whole piece. Same thing with this Blue Grass cabinet for me. What are the odds of finding one for general mechanics tools? It's that decal that makes the box! Picture it filled with Blue Grass marked pliers and nippers and screwdrivers and wrenches and that 'THREADING TOOLS' doesn't look so offputting anymore.
My biggest issue right now is brand-appropriate boxes or cases for the tool-sets I have building (e.g., the K-D I already mentioned, or Cornwell, or Williams, or PENENS, etc), so I could be looking at it through that lens.
