The Contractor 2 by 4 breaks ground with a whole different framework! One of the new breed of thematic knives originated by SOG, this knife is no apprentice. Open or close the blade and see the circular saw turn or rotate the saw and open the blade. Whether you are a contractor, know a contractor, or wished that you did not. The 2 by 4 will help on the job... whatever that might be. How many times have you wished to sharpen a pencil without having to walk back in the house? Or try and get that picture level without a level? The FF-01 is great for all kinds of quick jobs around the house.
