Query: Drywaller's Mate

The only reason I own this little gem is for drywalling. It fits in my pocket so I can whip it out to plane down drywall sheet edges quickly. That's important when your trying to fit them in difficult places like corners and closet ceilings, especially if you're standing on a bench or some other awkward position. It smoothes those edges and removes stock in a hurry. It pays to keep some extra blades around, though. Moisture combines with drywall dust to corrode steel, so the blades can rust between jobs. I wouldn't start a drywall job without this tool. Thanks..!
