How does a saw work?

The illustrations show how a saw works. What happens while cutting is being accomplished by the tips of the saw tooth which in two parallel cutting lines cuts it´s way down into the wood. To get these lines, the teeth are bent outwards from the blade, each tooth in the opposite direction to the one next to it. The cut in the wood is wider than the saw blade which prevents the saw from getting stuck as you cut and also allows you to make adjustments if you are going slightly off line. If the teeth are set to much, you will be removing more wood than you need; too little set, and the saw will probably jam or you will find sawing very hard work.

To get the real cutting ability the teeth has to be sharpened. This is today being made by computorized machines, which makes every teeth look the same. For the cutting ability, it is very essential that the saw teeth have exactly the same height and angel to create the above mentioned cutting lines.

Every other tooth cuts alternately in the kerf´s edge. The tooth has to be set to be able to cut like this.

By setting one could say that every other tooth should be set to the right and every other tooth to the left.

Universal toothed saws are very suitable as allround saws. Compass-, back-, veneer saws are all universal toothed.

Fleamed toothed saws cut´s very good across the grain, this type of sawing is being made in 90% of all the cases.
