I keep one of these in my truck. It's a pull saw so it cuts a lot easier than a typical hand saw with less binding and grabbing. The teeth look pretty fine but it will cut a 2x quick and easy. Also cuts PVC/ABS pipe just as easily. The pulling motion and fine teeth makes starting the cut easy, the wide blade keeps it cutting square. With the width and flexibility of the blade, and the shape of the teeth it also works good for flush cutting. It's fast and compact, easily my favorite hand saw.

I've had and used several 18v nicad saws of various brands, they work but was never something I really enjoyed using. They just run at too slow of rpm and always feel like they struggle.

The 20v Dewalt or pretty much any equivalent brand that is powered by the new lithium battery packs is MUCH nicer to use and worth every penny. DeWalt's brushless circular saw is almost like using a corded saw. The 20v is very good, the 60v is exceptional.

For $35 you can buy the 20v to 18v adapter and be able to use the new slide on lithium batteries with most of your old 18v tools! The old 18v saw would show improvement with a lithium battery but it will NEVER compare to the newer version with a brushless motor.
