This is the second shark saw I have owned.  I bought the 1st one about 10 years ago and it still cuts like it was brand new.  These tools are excellent for getting into places where electric tools won't get to with greater precision.  If you store them carefully you will get years and years of use out of them.  They are excellent for trimming door jams for putting in tile or new wood floors just set the tile or wood down and the saw will do the rest.  Since these are pull saws they are easy to get started with just 1 or 2 pull strokes.  Excellent hand tools for an excellent price.
