The no. 4's last bought came today. They were either from the 1940's or 50s. I hope you can see the lines in the picture. I sharpened one, and drew lines all over a rough cut Cypress board in two directions. After that, the last line I made is the one going a different direction than the others right off the end of the pencil point. The last line is maybe 2 thou wide. All those lines were made with that one sharpening, and you can see what's left of the pencil point.
They really don't make them like they used to.
I have no idea how to work with lacquer thinner on something like this. How would you suggest applying it, and do I wipe it off? Do I need to let it dry before sanding? Thanks in advance!
