I'm going to be using the scary sharp system
I've been looking at the scary sharp system myself. Haven't done anything about it as yet, but I did come across suggestions that it might not be the best choice for gouges or for very narrow chisels because of the risk of corners "digging in" and ripping the sheets.
I had been considering gluing the sheets to shaped blocks of wood to get a perfectly fitted slip stone. Then I discovered what you can accomplish by using your gouge to cut a hollow in the face of a wood offcut and inverting it to round over a corner. When you apply chrome polish to the shaped wood and rub your gouge over it. It doesn't take long to get a respectably polished edge.
Its only for finishing an edge, not a full sharpen, but I thought you might find it of interest - if you haven't heard of it before!
