They're back...
 

Those of use who were builders decades ago probably remember the Dubro Kwik-Sand Hand Sander. They were/are extremely handy.

I was building something a while back, discovered that I needed a new one because I dropped mine and bent the corner, and I was unable to find any of them, anywhere at all at the time. Then I saw an ad for these in a magazine a short while back. I ordered the long and short version about 2 days ago, and received it today with the least expensive shipping option.

You can order them directly, as I just did, or find them at most r/c retailers. When I run out of the sandpaper that comes with them, I always just cut new sandpaper out of a full size sheet, after I glue it on with rubber cement. I let the glue dry a while, then come back and run a razor blade down the side of the sander, to trim off from the full sheet what is now glued to the sander. I now have 3 long ones and 2 short ones, so when I need to change grits, I just pick up a different one. I will reserve my new, unbent ones for more precision work, and will be extra careful to not drop these.

I have the GP's version and the Dubro. They should have never stopped making them in the first place!
