It would help if you gave additional dimensions of the material you want to cut.

That said, how about “Rockler’s Miter Trimmer” (http://www.rockler.com/product.cfm?page=6533&site=ROCKLER)?

For the last few years “The Woodworking Shows” had a person demoing how to make your own inlay. He had a device that used a razor blade to cut very thin strips of materials. One device cut stright strips and another allowed cutting curved strips.
