Ted,
Here is a tool rack design that you can modify for your stamping tools. It allows you to rotate the tools at 2 different angles as well as providing the ability to carry your stamping tools and your swivel knifes. If you are interested in other types of tool holders, then consider pegboard organizers. If you go to the Marble slab thread you will see some PDFs on a workbench that you can tool on that allows you to sit or stand. It also has pegboard organizers on one side for various tools.
Regards,
Ben
