jimtown54,
I like Sack-Ups, they aren't great for transporting your knives, more for storage. They have rolls that hold 12 or 18 small to medium knives (up to about 5" folded). They also have individual cases that will hold larger folders.
They do a great job of protecting your knives but don't display them well.
Do a web search for Sack-Ups, you'll find them.
Hope this helps,
Steve-O
