This video is part 1 of 2, and covers some basic saw use techniques. This first video focuses on working with smaller pieces of wood.
Please keep in mind that saws, just like all other cutting tools, get dull over time. Properly sharpening a saw can be a complex procedure, and is one with which I am not sufficiently familiar, so I will not try to go over it here. Taking care of your blade will give it a long life, and these days, particularly with smaller saws like the ones you see in the video, most people simply replace the blade rather than sharpening it.
