spent the day messing about with this, saw something similar and wanted to have a go at one myself. its specifically to make field sharpening scandi's a little easier. made up from scrap i found in the shed its not pretty, just functional. 11.5" total length with an 1" x 8" plattern. i stuck a bit of leather on the side for stropping.
basically secure an 11"x 1" wide strip of sand paper with the end clamps then adjust the tension on the paper till tight.
