Cpirtle,
The cabinet in my mind is sort of like your's, so I have some questions for you if you have a moment. I'm thinking the top section will be a wood armiour-type deal - open it to expose large display area for knives with stands, and inside the doors would be thin display shelves. The center section would be drawers like your's. The bottom section would be cabinet-type storage like your's, for storing boxes, sheaths, etc.
How do you keep the knives from sliding around every time you open or close the drawers? I'm thinking my drawers would need dividers of some sort.
What are the dimensions of your cabinet? I'm thinking mine will be 30-36 inches wide, 24-30 inches deep, and 6' tall.
Was it hard to build? I'm not much of a carpenter, but I have a good selection of woodworking tools.
Does your cabinet have a lock of some sort?
