I needed a small (portable) and cheap chamfer plane for a wood working project so I designed this to work with disposable, readily available utility knife razor blades. After playing around with it for a bit I further modified the design to allow the blade to slide and stop in various positions to ensure that the sharpest possible edge is always cutting the chamfer.
The pictures are of the Alpha version which had some issues. I'll upload pics of the Beta version eventually.
