Well, indeed.
Though this all raises a further question. I need the pencil to mark-out the "pins" on a lap dovetail. I cut the tails first and then use that side to mark the complimentary member, as it were.
Now, I think that I'm supposed to use a marking knife but I'm not sure about that. Firstly, I'm sure I was told not to use a knife on end grain. Secondly, I'm still not sure I could see it properly unles the cut was quite wide (maybe I need more light!). Finally, I find when I mark like this, if I then cut the joint so that the lines are gone, the joint is too loose: with a pencil line, of course, I can cut just within it and fit the joint carefully.
For this kind of precise marking, I guess that an eyebrow pencil would be too chunky. Still, now I know why so many woodworkers are fascinated with boxes ... they're for all that make-up! :lol:
