The bottom and top of each one does have a slight bevel it is just not visible with the angle of the pic. The front and back edge not so much and they are somewhat thicker than the originals because I have big hands and I wanted them a little thicker. I do agree now that you mention it that I should have beveled the top and bottom more and added more of a taper to the front and back edges.
As far as the spacing of the lines they are at 16 lpi which as far as I know is about as wide as they come. Normal is either 16, 18, 20, or 24 lines per inch. I suppose you could hand space them and cut with a single line cutter but I used a tool that puts it to 16 lpi. There are cutters that leave a flat top diamond but I am just getting started in this. Maybe someday.
Keep the critiques coming. That is just what I wanted.
