Nice idea having big numbers and at least they narrowed the markings to a point on the edges. I also like to use a knife for fine stuff (fitting an inside piece for example), but I also like the thin, orange painted Home Depot pencils for marking less precise measures. I keep a sharpener on hand to give a super sharp point. Buy them by the dozens and got an artist's sharpener that makes a very sharp point and doesn't break the lead. I like the very dark mark they make and the line is very fine. I haven't tried a .5 mm mechanical pencil because I constantly break the .7 leads, and of course the pencil is always somewhere else when I need it--but that's memory, not pencil.
The more I do, the less I accomplish.
