This little sanding block is extremely handy. There is a round end and a flat end to match whatever shape you are sanding. If you are covering boards with paste paper or book cloth, you can chamfer the sharp edges in no time at all. It holds sandpaper that comes on an adhesive-backed roll. When the end-in-use is ready to be renewed, you just release the worn part and pull out another five inches, stick down the new part, and tear off the used piece. It doesn't take up much workbench space and does exactly what it is meant to do.

I have had two of these in use for a number of years, and now have treated myself to seven more, so I can have one set up with every available grit. I'm going to color code the labels so I can work through the rainbow when sanding wood to a fine finish.
