I use a combination of nylon knife cases and Rubbermaid containers. The nylon case holds 22 full size folding knives. Here is a link

I would recommend going with a Benchmade 275 Adamas. It's a folder that will satisfy your need for a fixed blade. You can grab one on sale at cutleryshoppe.com for $124.31.
