While making a knife I needed to clean up a pretty sloppy first attempt at freehand grinding the primary bevel so I made a jig to use to keep the file and the blade in the same orientation while hand filing. Mine is made of two independent pieces held in parallel in my twin screw vice. It's made of some pine and a little bit of walnut I had laying around.
