Sanding Screen Speeds Sharpening

THE WINNER:

For a chisel or plane iron to be truly sharp, its back must be lapped flat, then polished to a smooth finish. This initial lapping step tends to be the most tedious part of sharpening and I'm always looking for a quicker way to do it. In the past, I've used wet/dry silicon-carbide sandpaper, but I found that it tends to slightly round the back of the tool.

I recently discovered that a#l 20-grit "sanding screen" - an inexpensive product used for smoothing drywall - works great for the process. Available at home supply stores, the screen cuts very aggressively and the openings allow the honing "swarf' to fall through without building up on the surface. I place the screen on top of a piece of #400-grit wet/dry sandpaper that I adhered to a sheet of plate glass using spray adhesive. After lapping the tool on the screen, I use

the #400-grit sandpaper underneath as the next honing surface in a sequence that continues up through finer grits until I have a finely polished surface on the tool.
